Boomershoot 2008 site maintenance and conditions

On Saturday Caleb and I visited the Boomershoot site to do some maintenance, explosive experiments, and to inspect the site.

The maintenance went fairly well. I discovered why one of the WiFi access points wasn’t working. It will take another trip out there to verify my fix but I’m pretty confident it will work. The new inverter I had installed last fall didn’t want to start up until after we fiddled with it for quite a while and I don’t trust it. I’m going to get another one. And finally we installed a petcock on the pipe for our “well” so we could easily drain the water out of it.

The explosive experiments went well enough. We mixed up two batches of Boomerite. One was made with the old fertilizer grade ammonium nitrate. The other batch used the new explosive grade ammonium nitrate I purchased last June. We did a quick test with the new stuff last September and suspected it was not as sensitive as the older material. Our tests on Saturday confirmed those suspicions.

Using CCI Stinger .22LR ammo from about 65 yards the old would detonate reliable but the new would only detonate about one out of three hits.

Using American Eagle .22LR ammo at 12 yards the old would detonate about one out of three hits but the new would not detonate even one out of five or six hits. At 10 yards the old would detonate every time and the new only about one out three hits.

Our conclusion is to get the same probability of detonation the new material requires about another 10 fps of velocity. This is measurable but not a big enough deal to spend the effort to try and improve the mix.

The biggest issue I have concerns about is the condition of the site. It was five weeks from the big day (April 27th) and there are still drifts well over knee deep in places.

This is the road leading into the parking area and a neighbor’s car.

This is The Berm shooters use for prone shooting. That snow drift is probably two to three feet deep.

This is the hillside shooting area where targets in the 500 to 700 range are placed. There are some big drifts out there.

I’m really glad we paved the target construction area with concrete blocks last fall. This will keep us out of the mud.

This is the 375 yard target area. It is very, very wet and muddy.

I spent some time talking to my brother about the ground conditions.

My brother Doug and I talked for a while about the weather. He is of the opinion it would take about three weeks of good weather to dry up to the point where they could start farming. If they can be in the fields we would have excellent conditions for Boomershoot. However, the weather forecast for the next ten days is for rain and cloudy weather. Therefore my best guess is that Boomershoot 2008 will be on the damp side. I’ll visit the site again at two weeks and one week prior to the event and have better information. Attendees should have contingency plans for muddy ground unless I give a better report just before the event.

Caleb spotted ten wild turkeys as we were headed home.

  1. You are on the right track with your admission you are from Florida. Were you also a victim of public schooling? 🙂

    [Transitioning to full Asperger’s mode.]

    At a temperature of about 32F (0C), depending on the pressure, the H2O molecule undergoes a phase change. Below that temperature, called the freezing point, the molecule is a crystal. Above that temperature the molecule is a liquid. The crystal form of the molecule has a high index of refraction. This causes it to reflect light and sparkle similar to a diamond. During the winter months this part of Idaho receives sufficient quantities of this molecule falling from the sky in the crystal form to completely cover the ground and pile up to substantial depths. In the winter of ’69/’70 there occurred up to 12 feet in wind driven accumulations we call “drifts”.

    In the spring these crystals undergo the phase change to a liquid with the higher temperatures. The liquid form of the molecule causes the ground to be come very soft which makes travel across unprotected ground, including simple walking, difficult and messy.

  2. Sunny and warm here in California, too. I actually think shooting Boomers in the snow would be lots of fun. Probably not so much fun for Joe to set up, though.

  3. Joe, if you could do it in the quarter acre that is my yard, I’d do it in a heartbeat.

    See, we trade nice weather for having to be packed in with our neighbors. Which also means on occasion you have to watch your older, overweight neighbor prance around in a speedo from time to time.

    Did I mention it was in the high 70’s today>

  4. If it’s “really, really muddy” your pickup wouldn’t make it to the line.

    I probably exaggerate the adversity the shooters will experience under worse case conditions. The Boomershoot staff are the ones who will experience knee-deep mud while placing targets and doing various other tasks. The shooters will have well established sod that will keep them from sinking out of sight but it could be wet and cold.

    As of this minute, nearly 1:00 PM, it is 28F in Moscow and 36F in Orofino. Orofino is about 2000 feet lower in elevation and Moscow is about 400 feet lower than Boomershoot. Therefore I would expect Boomershoot to be in the range of 25F to 28F today.
