Boomershoot is a long range precision rifle event with high explosives as the targets. This is about Boomershoot in general and sometimes just explosives.

Boomershoot 2010 to be on T.V.

Posted on by

As others have noted Michael Bane has announced he and his film crew will be attending Boomershoot 2010. I’ve known about it since mid-October when he sent me an email that said, in part:

I want to give you a heads up…I would like to film Boomershoot 2010, if it works for you. It would either be for my flagship, SHOOTING GALLERY, or for a new show I have in the works under the working title of AMERICA SHOOTS! You’d rather have it be AMERICA SHOOTS! because it will be hosted by the hysterically funny an spectacularly beautiful Katie Rowe, a professional stuntwoman and obsessive shooter.

Again, if it works for you, I’d like to put together some live coverage on DOWN RANGE (www.downrange.tv).

I held back on announcing it because I wanted to the plans to be a little more firm.

I don’t know his exact schedule yet but I’m hoping he will cover the target making on Saturday too.

Another Boomershoot slot opens up

Posted on by

We had another cancellation for Boomershoot 2010 yesterday.

I sent email to all the existing entries informing them they could swap their current position for the one opening up.

On Tuesday at 6:00 PM PST I will make the empty position available for the first person to sign up at http://entry.boomershoot.org/.

I don’t know for certain which position will be open. The canceled position was #32 but if someone wants to swap that could change.

Some hints on signing up:

  • Sometime several minutes before 6:00 PM on Tuesday go to the web page and put in your name, phone number and other entry details.
  • Click on the button labeled “Update Price”-this sets the cookies in your browser so you don’t have to reenter that information when you come back to the page or refresh it.
  • A 6:00 PM go to the page and find the available position (I’ll send out another email when I know for certain).
  • Refresh the page repeatedly until the position button labeled “Position 32” or some such thing is not grayed out.
  • Hit that button as soon as you can.

Last time I did this the first position to open up was snatched in 32 seconds. I don’t expect it will take much, if any, longer this time.

I hope it doesn’t reduce the attraction of Boomershoot but it was the lesbian couple that canceled due to one of them starting a new job and being unable to take time off so soon.

Update: Yes, I was trying to make a joke about the lesiban couple.

Also, position 32 has been take but position 74 is now available for swap.

Boomershoot article in Motorcyclist magazine

Posted on by

Via email from veteran Boomershooter (he was at the FIRST Boomershoot in 1998) Steve M. and the author of the article, Jack Lewis, I found out the March 2010 issue of Motorcyclist magazine has an article about a trip to Boomershoot 2009 from the Seattle area on a motorcycle with a sidecar–a 2WD Ural Safari.

It includes a lot of photos (by Shasta Wilson) and is a great story. It includes typical Boomershoot experiences like:

Bundling Pretty Wife into fuzzy blankets, I tossed two cased rifles across her chest and we were off.

“Don’t worry, ” I bellowed, “It won’t rain in the mountains!”

It didn’t rain. It snowed.

I bought out the entire supply of the issue at the newsstand in the lobby of the Crossroads Mall in Bellevue, WA and they said they are unlikely to get any more in. The Barnes and Noble next door only had a couple of February issues when I checked on Sunday evening but if you check there now they might have one.

The article starts on page 70.

I love engineering

Kevin has the story.

I just want to add that my degrees are in Electrical Engineering but when I worked for the Aerospace Division at Boeing a lot of my time there was in the “Terminal Guidance Lab”. Now at Microsoft I work on “location for cell phones”. In my spare time I play with my chemistry set and make targets.

It’s almost as if Kevin was talking about my career.

Gone in 32 seconds

Posted on by

There were three positions that opened up for Boomershoot 2010 in the last couple weeks. I made them all available at precisely 6:00 PM PST.

That didn’t last long.

Position 18 was gone in 32 seconds.

Position 47 was gone in 5:47.

Position 50 was gone in 8:45.

It didn’t hurt that the KING 5 Evening Magazine video ran again in the last day or two. I got a calls and email about it.

Two Boomershoot 2010 positions to open up

Posted on by

I have cancellations for two positions at Boomershoot 2010. Both positions are on the Berm and will open tomorrow evening, January 26, at 6:00 PM PST (the same time as Gun Nuts Radio comes on).

The pictures for these positions may exaggerate the view of part of the tree-line (375 yards away). I extended the berm further to the left to make each position a little wider. I didn’t notice it at that time but the view of the targets on the right is obstructed. I should have made the extension a little higher. You will be able to see about 1/3 of the tree-line targets and all of the hillside.

To sign up for a position visit http://entry.boomershoot.org/ tomorrow evening.

Update: Lots of changes are happening. Existing entrants have requesting positions swaps. I had another cancellation. A .50 caliber position is going to be dedicated to hourly use. Position #31 may be available as well as one Berm position.

Proposed mini-match at Boomershoot 2010

Posted on by

A recent email from RivrDog contained the following:

The Rivrdog/Rockett Boomershoot camp (camped at #75/76) issues the following Challenge to those coming to this year’s Boomershoot, INSTRUCTORS INCLUDED!

  1. Pick any off-the-shelf HUNTING rifle out of your safe (or buy one, except no Fifties at this end of the range). Custom rifles OK, if they are custom HUNTING rifles. I’ll have a scale, your rifle needs to weigh less than 10# to qualify, or you need to prove you actually tote that 17# monstrosity in the field and not just shoot it off a bench (photo of you with the elk and heavy rifle will do). I’ll be firing a WIN70, myself.
  2. Put any glass on it you desire.
  3. Load/buy any ammo for it you desire (that doesn’t conflict with Joe’s rulz).
  4. On Field Fire days/hours (Friday and Saturday), come on down to the Rivrdog/Rockett camp and use MY shooting table & rifle rests. The rests are elevation adjustable front and sandbag rear. Coordinate your rifle -moving to be legal during cease-fires.
  5. Bring your spotter or go solo.
  6. Fire 10 rounds, slow fire, at the right-end steel ON THE 380-YARD BERM. Number of hits on it is your score.

Winner receives a (new, sealed!) bottle of 12-year old Scotch, my choice (which guarantees it’s quality!). As in war, no second place prizes. My guess is that it will take no less than a 9 to win, so put in some practice time. You likely will be shooting against some professionals. The steel will be about 2 MOA, if it’s like last year. I may bring a 1 MOA steel for tiebreakers. Award ceremony after Field Fire/Cleanup on Saturday. I will take photos during the contest.

If I had the time that day I would show up with my 17.5 pound Spud Gun that I used the one and only season I went hunting (and got a deer). It can do this at 200 yards and hitting 2 MOA (about 8″) at 375 yards is pretty easy if the wind isn’t bad. I’d do it just to be pushing the envelope on the rules and winning, not because I’m interested in a bottle of Scotch. I’ve never tasted the stuff and am not particularly interested in trying. Besides I have two bottles of the stuff on the shelves (Xenia, you still have that one bottle, right?) given to me by friends that I haven’t touched.

If you happen to think of some nifty addition to the proposal suggest it to RivrDog. This is his baby.

I’ll probably get around to emailing this to all the participants sometime this weekend.

Survival list

Posted on by

Via email from MD Creekmore I received a link to this list of survival related materials. It all seems to be pretty straight forward and obvious stuff. I found the headings on the “Survival Guns” list somewhat amusing:

I work at Wal-Mart Arsenal
  1. Mosin Nagant 91 rifle
  2. Single Shot .12 gauge
  3. Smith&Wesson model 10
The Government Welfare Arsenal
  1. Short Magazine Lee-Enfield
  2. Mossberg Maverick 88 12 gauge pump
  3. Smith&Wesson model 10
  4. Ruger 10/22
I have a full time Job Arsenal
  1. Ruger Mini-14 Ranch Rifle or AR-15
  2. Mossberg 500 12 Gauge
  3. Glock Model 19
  4. Ruger 10/22
Two Jobs and Maxed Credit Card Arsenal
  1. Ruger Mini-14 Ranch Rifle or AR-15
  2. Remington 870 express with spare riot barrel
  3. Glock 19
  4. Ruger 10/22
  5. Winchester Model 70 in .308 Win.
  6. Taurus CIA Model 850 .38 SPL. Revolver
And Finally the Yuppie Survival Arsenal
  1. L1A1 Rifle chambered in .308 Winchester
  2. Remington Model 7 bolt action chambered in .223
  3. Winchester Model 70 in 308 Win.
  4. Remington 870 express with spare riot gun barrel
  5. Colt 1911 A1 .45 ACP
  6. Taurus CIA Model 850 .38 SPL. Revolver
  7. Savage Model 24F .223 Remington over 12 gauge (if you can find one used)
  8. Ruger 10/22

I do question the need for both a revolver and a semi-auto pistol when both perform essentially the same in terminal ballistics, range, concealability, portability, and availability of ammo.

Also of possible interest is that if you are in the Seattle or Moscow Idaho area I can get you wheat, lentils, and split peas in large quantities cheaper than you can find it almost anywhere else. People attending Boomershoot can arrange for pick up at that time as well. Send me an email with the commodities and quantities you are interested in. The smallest unit I’m interested dealing in would be 50 pounds of any one item.

Boomershoot 2010 Precision Rifle Clinic

Posted on by

Details on the Boomershoot 2010 Precision Rifle Clinic are now available. You don’t have to participate in the main event to get coaching and shoot in the clinic.

The clinic fills up every year and Gene has lots of repeat attendees so you know people are getting their money’s worth.

Sign up and learn how to turn money and time into earth shaking noise and smoke.

As a side note, Boomershoot statistics are here. Probably most interesting is that there are 110 participants and we have 11 bloggers-exactly 10%.

We will be having a blogger/media day again on Thursday April 22nd.

Chemistry experiments

Posted on by

This last week, for the first time since 2005, I had both an idea for increasing the sensitivity of Boomerite and the inclination to test it. Son-in-law Caleb was eager to go with me and we planned an experiment which I hoped would reduce the activation energy to get detonation. Tim also expressed an interest so on Saturday I loaded up the car with a lunch and my test tools (a chronograph and a Ruger 10/22).

Caleb wasn’t feeling well but Tim went with me and we performed a bunch of experiments. We mixed up the standard mix for a control and got the expected results. The next mix demonstrated that my “great idea” was a total bust. It was still morning and the entire series of experiments I had planned was pointless. I looked around on the “top shelf” in the Taj and saw something I hadn’t tested in the mix before-sulfur. So we first added 20 grams of sulfur to a batch of Boomerite. It seemed to help.

We added 40 grams and it was definitely more sensitive.

We added 80 grams and it didn’t seem to make much, if any, difference from the 40 grams.

We mixed up a batch for storage testing and locked it in the magazine for safe keeping.

After arriving home that night, just as I drove in the driveway I remembered why I had never done those tests with sulfur before. Even minor impurities of sulfur mixed with potassium chlorate and moisture can cause a runaway reaction resulting in a fire. Spontaneous combustion of explosives just sounds so wrong. And I had forgotten that.

I rationalized that it was cold (near freezing) and that lack of moisture in the zip-lock bags probably would keep the Taj Mahal from going up in flames before morning and I was able to get some sleep.

The next morning (yesterday) Barb and I drove the hour out to the site, removed the five pounds of “New Boomerite” from the storage magazine and burned it.

Well, at least Tim and I had a little bit of fun converting money into noise.

Barb says she married a rock star

Posted on by

On Friday I was in the local Safeway store when from across the produce department someone caught my eye and called out, “You’re Joe Huffman, right?”

I sort of recognized him. I had bumped into him numerous times at the Seattle airport back in the late 90s when I was flying back and forth to/from Redmond/Moscow (ID). Tim lived in San Francisco then but had gone to college at the University of Idaho and his girlfriend was still there. So he frequently spent a weekend in Moscow with her and would take the same flight on the same small plane from Seattle to Moscow that I did. We had another common connection in that his buddy Seth that he went to high school and college with was then his roommate in San Francisco had worked for me when he was in college at the U of I.

Tim told me he would love to do some Boomershoot stuff sometime and if I ever wanted some help to let him know. I told him that I was thinking about going out on Saturday to do some tests and he would be welcome to come along. He sounded very interested.

Later in the day I was hitting up all the places that sold ammo in town looking for some CCI Stinger ammo. I use that for testing of the sensitivity of Boomerite. By moving closer or farther away I can adjust the impact velocity at the target and determine if the mixture is more or less sensitive that other mixtures I have used. At one of the stores I was asked what I was looking for and I told him. He said he was sorry but they didn’t have any. Would one of the other products they had work instead? I told him no, I needed some very high velocity stuff. “What are you trying to kill?”, he asked.

[heavy sigh]

Do I tell him the truth or avoid the question? This has happened so many times. Buying 15 boxes of zip locked bags, or a 50 pound sack of stuff at Costco can make people curious and I always worry they won’t want to sell to me or they will call the cops and I’ll spend an hour or five explaining to them.

I told him the truth and his eyes got big and instead of backing away he said, “Are you the Boomershoot guy?” I confirmed it and he introduced himself, shook my hand, and told me how pleased he was to meet me.

I went home and told Barb that two people in one day recognized me. With a big smile on her face she said, “I’m married to a rock star.”

Somehow I was under the impression rock stars had more groupies. I’d put some effort into increasing the number but I’m afraid the number would drop from one to zero at the first indication I was making the attempt.

Another step closer?

Posted on by

One of my fantasies is to be able to make Boomershoot targets completely out of very simple and easy to obtain materials. For a while I was essentially there. I could get ammonium nitrate by going over to the local fertilizer plant with the truck and telling them to “fill ‘er up” and they would dump in as many tons as the truck would hold and I could pay for. The potassium chlorate was a little harder but with just my drivers license I could get that mail order without hassles. The rest could be obtained at the grocery store or Wal-Mart. Then ammonium nitrate started getting difficult to get. I had to use the leverage of my ATF type 20 license to manufacture high explosives to get my last batch of AN. And in the quantities of potassium chlorate we consume the suppliers require the ATF license as well.

But there might be something else as possible replacements.

They are making rocket fuel out of aluminum and ice:

Researchers are using aluminum and frozen water to make a propellant that could allow rockets to refuel on the moon or even Mars.

Last week researchers from Purdue and Penn State University launched a rocket that uses an unconventional propellant: aluminum-ice. The fuel mix, dubbed ALICE, is made of nano-aluminum powder and frozen water, and gets its thrust from the chemical reaction between the ingredients. The propellant is environmentally friendly, and it could perhaps allow spacecraft to refuel at locations like the moon, where water has been discovered.

That is majorerly cool from the standpoint of rocketry and space travel. But it also has implications for Boomershoot. Any high energy compound or mixture has the potential to be an explosive. Rocket fuel in particular is interesting because, like explosives, it contains both a fuel and an oxidizer.

Nano-aluminum powder might be tough to make but the precursor components of that particular mixture sure are going to be easy.

Boomershoot Wi-Fi working again

Posted on by

It turns out the external antenna isn’t working. It could be a bad connection or cable. I just don’t know for certain. I switched to the internal antenna on the station at the Taj and I got everything working. This probably will reduce the coverage at the shooting line but I can work on the external antenna problems some other time. Like next spring when the weather is a little warmer. Currently it’s 36 F and my fingers are cold. And if I am going to be replacing cables I want to have warm enough weather than the rubber tape I use to seal everything up with will stick and be pliable.

I also mortared the concrete blocks for the “throne” into place.

I think I’m done with all the maintenance I want to do here. The next trip out will probably be to do some Boomerite mixture testing. If the weather is good perhaps son-in-law Caleb and I will come out on Saturday.

Chronograph happiness

Posted on by

My first chronograph was something I bought about 15 years ago from an estate sale and it was old then. It died a couple years ago and the new one I bought was a CED Millennium. Because there were times in which the light started getting low that I had problems getting readings with my old chronograph I splurged and got the Infrared Screen Set with the new unit. Today I was glad I did.

I had used the IR screens  in near total darkness just to test them and got good results. But today it was just very dark and cloudy from the snow storm coming in. I put 10 rounds from my .40 S&W over the screens and got good readings but when I tried a .22 LR there was nothing. Rats! I really wanted those numbers too. I have been thinking there is something I could try to make Boomerite a little more sensitive and the normal .22 LR ammo I use for testing (CCI Stingers) hasn’t been in any of the local stores (I now see it is available some places on-line). I wanted data on some other ammo to see if I could replace the Stingers. CCI Velocitor was the prime candidate and I didn’t want to make another trip to the range or waste time getting chronograph data at the Boomershoot site.

I got out the inverter (every vehicle should have one), plugged in the IR screens, and every shot recorded a velocity.

I’m now very happy with the chronograph and IR screens.

In my rifle the Stingers clock in with muzzle velocities of about 1605 fps and the Velocitors at about 1320 fps. But from looking at my notes it appears that the Velocitors should detonate the targets at 25 yards even though they are quite a bit slower than the Stingers.

The point of the exercise today is to show you that have never before seen some explosives at work.

Believe it or not, everything you saw on T.V.–not 100% correct.

Explosives charge over the top

Posted on by

It’s a little hard to tell from the article but it appears a guy was making .223 shell casings into explosive devices:

Robert J. Heintz Jr., 36, of Deep Creek Road, has been charged with risking a catastrophe, unlawful possession or manufacture of weapons of mass destruction and recklessly endangering another person in connection with Friday night’s explosion. Heintz, who suffered a serious hand injury during the explosion, was arrested. He had been released from an area hospital on Sunday.

…

When authorities interviewed Heintz at the hospital, he claimed that he purchased .223 rounds off the Internet from Bulgaria and claimed that the tips were loose on the rounds, according to the arrest affidavit. Heintz allegedly claimed that he was attempting to place the tip back in place with a pliers at the time of the blast.

Heintz, according to the arrest affidavit, told police that he researched “some recipes on the Internet” and downloaded them on his computer. Heintz further claimed that he had mixed a batch using the instructions from the Internet and packed the substance into the .223 round, police alleged.

“He continued to explain that he attempted to ignite these rounds in his back yard with no success of detonation,” Moyer alleged. “Heintz explained that he went back into the house to do another round at the computer table, packing the recipe into the brass when the bullet exploded.”

He is being charged with possession or manufacture of weapons of mass destruction? That seems more than a bit excessive from the information I can glean from the article. I would have given him an honorable mention for a Darwin Award and told him to apologize to his wife for making a mess in the house.

Here is a hint for people that don’t want my nomination for Darwin Awards in the Explosives category. Don’t let metal come in contact with metal in the presence of explosives. Even if you don’t use metals that can create sparks the point of contact between the two metal surfaces generates tremendous pressures. Imagine one pound of force applied to your pliers that makes contact with another piece of metal on an area that is 0.010 x 0.010 inches square. That is 10,000 PSI. Those sorts of pressures, even when confined to an exceedingly small piece of material can initiate a chain reaction. This is part of the reason so many pipe bombers end up blowing themselves up. The threads of the steel pipe create extreme pressures and start a reaction resulting in the rapid dissasembly of the bomb builder a few milliseconds later.

Boomershoot 2010 fall prep done

Posted on by

Two weeks ago I delivered a bunch of concrete blocks, mortar, and grass seed to the Boomershoot site. I didn’t stay long enough to do anything with it because I wanted to shoot in a steel match that same day. I made the quick trip out there because I was afraid it would snow up or rain so much that it wouldn’t be accessible until spring and I wanted the materials out there so I could walk (or snowshoe) in if I needed to and do any last minute prep work.

Today I drove back out and planted the last of the grass. It wouldn’t have been disaster if I hadn’t gotten the grass planted but it will be better that I did get it done. I would have liked to have done some work finishing off the semi-permanent toilet but I ended up spending time talking to my parents and brothers and then driving the 345 miles back to the Seattle area.

I’ll probably go back out there in a couple weeks. Due to a huge office move at work I will have the entire Thanksgiving week off (extra, free, vacation!) so assuming the ground isn’t knee deep in mud or waist deep in snow I will spend some of that time working on the site. But I have 2010 essential stuff done for this fall.

So, do you still give chemistry lessons on the white-board in your office?

Suresh Parameshwar
October 15, 2009
[See also another time when I quoted Suresh.

Suresh was my mentor at Microsoft when I first started working there full time. Almost two years ago he left Redmond to go back to India (still working for MS). He was back in Redmond this week on business and stopped by to visit friends. A bunch of us had dinner at our old boss’s house last night and stay up talking until almost midnight.

Before he went back to India on more than one occasion Suresh and I had discussions about explosives and I explained the chemistry to him on the white-board.

The above question was one of the first things he said to me when I saw him last night.–Joe]
