The Double Auto Pistol

The 2011.


They say there have been many double barreled guns in the past, which of course is true, but the purpose has always been to have multiple shots available, either in leiu of a repeater (before there was any such thing as a repeater) or to have a second shot on hand without working an action, usually in a large African caliber or a shotgun.  In this case both barrels fire together.  It’s an interesting novelty.  Maybe you could fiber/epoxy a couple of 1911s together and have a similar experience.  The variations on the jam, or other stoppage, should be interesting as well.  The two barrels are serviced by a common slide.

Not Glocking so Glockily down the Glocky trail

My G20 quit feeding properly last summer, and I identified the problem as an original recoil spring that had gone soft.  A new Wolf spring and steel guide rod took care of that.  Then I wanted to try a new Lone Wolf barrel because I was getting so much case buldge that one use was about all I was comfortable with, and the LW barrels have more case support at the bottom under the case web area.  They also have standard cut rifling, which is supposed to better for cast lead bullets– something I’d like to try at some stage.


My first tryout of the new barrel led to a failure to feed the very first round, but after that it seemed to function normally and I figured all was well.  Not so fast.  Those were previously fired cases.  Last time out, with all new cases, I had several failures to feed, and had to bump the back of the slide to get it into battery.


This morning I tried feeding some rounds from several full magaxines, and here’s what happened;



Above is the slide resting quite securely, with its new, beefier recoil spring, on a jam.


Below, I’ve removed the magazine and locked the slide back.  That round is still wedged in the back of the chamber, and it took some fiinger pressure to dislodge it;



(Below) you see the mark below the case mouth, from the front of the feedramp digging into it;



My theory is that the new, softer cases are getting bitten more deeply than the work-hardened fired cases I tried the first time, resulting in more problems.  The original Glock barrel has much more “throating” or relief at the feed ramp area, which is why the Glock barrel is said to have less case support.  The LW barrel has more support in that area, but for now it doesn’t have enough clearance to feed reliably.  My new StarLine cases are trimmed at the factory to only a few thousandths over the minimum, and about 7 or 8 thousandths under the maximum case length.  The overall cart length is exactly, to within two or three thou extreme spread, what the Hornady manual (and several others) called for.  The rounds plunk right into the LW chamber with the barrel removed, but jam in the chamber when fed from any of several magazines, due to the feed angle and the tighter (actually just longer at the bottom because of less throating) chamber.


A longer bullet ogive might force the front of the cart down as it feeds, but at the moment I don’t know if that would help or hurt.  I might just put the perfectly good old barrel back in and live with super short case life for now.


I spent 30+ years doing custom work on various types of musical instruments, and long ago came up with an axiom I have repeated many, many times to perspective customers and fellow shop workers;  When you divert from the original design, expect a cascading series of unforseen problems.  In other words, expect to pay through the nose as we may have go back to the drawing board a time or two, to find ways to accommodate your custom thingamajig, making it work seamlessly with the rest of the system.


I noticed just yesterday that Brownell’s, I think it was, or maybe it was CTD, had a bunch of LW Glock barrels in a promotion, for all the Glock models except the 20, or those in 10mm.  This kind of sucks, because I was having a ball late in the summer shooting silhouettes at 100 yards.  The original barrel never seemed to give enough accuracy to make that a reasonable proposition.

[I]t’s widely known that anyone carrying a Glock has mental issues. In fact, I’m surprised that potential Glock owner’s aren’t disqualified by default when filling out the 4473 form!

Mocking the Brady Campaign

Barron continues our video series and posts mocking Brady Campaign Board member Joan Peterson with Pumpkins for Joan:

Think about this… The Brady Campaign wants to, and has tried for decades, to get various types of guns banned. Handguns were their first target back in the 1970’s. They were originally the National Council to Control Handguns (NCCH), then the Center to Prevent Handgun Violence (CPHV), then Handgun Control, Inc. (HCI) in 1980 and finally The Brady Campaign in 2001. And as recently as the brief they filed for the DC v. Heller case in 2008 they claimed the Second Amendment did not protect an individual right and even if it did it did not extend to handguns. Not only have they failed in their decades long mission the U.S. Supreme Court has explicitly said handguns are protected. And using the phrase “in common use” the court strongly implied that the secondary target of the Brady’s, “assault weapons”, are also protected. They have some extremely high hurdles to overcome to even get back to the position they were in as late as 2008, let along where they were when they were founded in 1974. And today on our side we use not only “assault weapons” but explosives to mock them.

When guns and bullets just aren’t enough aren’t you glad we have Boomershoot?

Priceless

Barron made another video for Brady Campaign board member Joan Peterson. Read his blog post for the complete story with this as the dessert. It’s dessert because it is sweet (even if Barb L. says it can’t be dessert because there is no chocolate):

I’m working on a video of my own from last weekend. It will have a different focus but it still should give Peterson heartburn. Some people don’t like just desserts.

Shelley Rae: On Target with ESS Boomershoot Vol. 3

This is the third in the series of ESS Boomershoot videos. At about 1:30 in the video watch the trace from the bullet arc into the boomer for a detonation. Very cool.

From the YouTube page for this video:

Boomershoot: In the high Palouse of northern Idaho for one long weekend in April, the ground heaves with explosions and precision rifle and AR enthusiasts put their aim to the test.

That’s a good description. Perhaps “rumbles with explosions” or “vibrates with explosions” would be better than “heaves” but there is some ground heaving too.

There is also Volume 1 and Volume 2 in the series.

As I have said before ESS makes good stuff. They gave me a couple pair of their glasses and I use them whenever I need eye protection or even sunglasses.

Barron also has some comments on the video.

Quote of the day—Kris R

Of all the things I have been able to do while in the United States of America, celebrating Halloween by shooting a pumpkin filled with Joe’s special blend is one of the things I will treasure the most.

Comment to I agree with Joan Peterson.
[It’s nice to have such an event be remembered so fondly.

I wonder if the anti-gun people get reports like that for their events. No, I don’t think so either.—Joe]

You think you’re a gunsmith?

THIS is a gunsmith.  Watch all of them.  There are a bunch of vids all in a row detailing the handcrafting of an American longrifle.  They hand hammer a barrel around a mandrel and hammer weld it.  Awesome.  No “machine tools” of any kind.  The closest to a machine tool is the barrel drilling jig, which is hand powered and hand fed, using hand-made cutting tools, and having a wooden spiral jig for determining the rifle twist.


Hat tip; castboolits.gunloads.com


We are extremely pampered today by comparison, having rolled bar and seamless tubing of precise alloy to work with.  I once “restored” (though the word is abused in this case) a hand-made, lavishly hand engraved and gold plated trumpet that was made in the very early 20th century– for its original owner, who was over 80 years old at the time.  He had bought it as a kid and played it the whole time.  All of the tubing was wrapped over mandrels and soldered, including the piston valves– every tubular part had a lengthwise seam therefore, and some of the silver solder had corroded out, resulting in leaks.  I had to re-solder some of them, but others were too far gone and I replaced them with extruded, seamless tubing.  The curved tubing was made back then by filling the straight pieces with lead and bending them  by hand over a bending jig, then hammering out any wrinkles.  Now they are bent using an ice composition and then hydro-formed in molds.  Some curved tubular parts are now built up entirely through electrolysis over investment cores.  And they didn’t use a buffing machine back then, but instead hand-burnished every square millimeter of the instrument prior to plating it– you could still see all the tiny facets on that trumpet– one for each stroke of the burnishing tool.  But that all that was still short of the skills used in rifle making in the 18th and early 19th centuries, and I didn’t do any engraving, carving or inletting in my instrument repair career.


An instrument (or rifle) with that sort of craftsmanship today would cost you well in excess of fifteen thousand dollars (you find fine rifles for well over a hundred thousand) though we can get good ones, made by modern methods, for under one thousand.  But no one makes musical instruments like that anymore, so far as I know.


When I first started in musical instrument work, the most expensive saxophone, the Selmer Mark VI, was under a thousand dollars, or right around a thousand, and it was imported from France, but the much simpler concert flute could be found costing several times that much, made in America.  You know why?


Because a flute can be made by hand in a person’s basement, whereas it takes a rather large shop, with a tons of specialized tooling, to make a saxophone, that’s why.  There were exquisite hand-made flutes, but no hand-made saxophones.  You can’t hand build a large-scale integrated microchip in your basement.  It may cost millions to set up for making them but you can buy one for a dollar.

I agree with Joan Peterson

It’s a rare thing but this time I (partially) agree with Joan Peterson on this issue (H/T to Sebastian). She says, “Don’t carve pumpkins with guns”.

I took two almost new shooters to Idaho this weekend to do a little pumpkin “carving” at the Boomershoot site.

First we prepared some chemicals:

IMG_2968_2012Web

Then we mixed them. Yes, she was a little apprehensive at first. This whole Kitchen Aid mixer making Boomerite is a little “different”. Six weeks ago had you told her she was going to be traveling to Idaho, making explosives to “carve” pumpkins, and shooting a rifle before Halloween she would have said, “No way!”

IMG_2964_2012Web

Here are some sample pictures of the pumpkins being “carved” (thanks to Barron for bringing them to the party):

The picture below was taken a fraction of a second after the picture above. Notice that the pumpkin pieces have slowed and are further from the origin. I wonder what the BC of a pumpkin seed is.

There are hazards to pumpkin “carving” with Boomerite. Max wasn’t really “entertainingly close” by some peoples standards but it was close enough that he sometimes turned away to avoid getting hit in the face with pieces of pumpkin. I was extremely pleased that his finger came off the trigger and he kept the gun pointed in a safe direction:
IMG_3264_2012Web

I’m sure Ms. Peterson will be pleased to know we didn’t use guns as our primary tool for carving the pumpkins. It was just the remote detonator for the explosives. And these new shooters will share their experience and pictures with friends and family which will add to the set of people who recognize modern sporting rifles in common use are not “assault weapons” which should be banned. But instead many of them will desire their own and to share in the fun of the gun and Boomershoot culture. And what does Ms. Peterson and the Brady Campaign have to counter this?

Boomershoot brings out the smiles.

Did you see the smiles after connecting with the 650 yard boomer? I am of the opinion Boomershoot is a valid treatment for depression and should be covered by most health insurance.
