Keeping it Complicated

Anything Worth Thinking About is Worth Overthinking

I don’t feel like being responsible just yet. I think I’ll write about some trivial things.

My reloading efforts ran into a speed bump. I have been trying to create 10mm cartridges with 180-grain Speer Gold Dot bullets, and I want 1225 fps from a compact Glock.

This should be simple. I did it about 10 years ago. I may get scolded for saying this, but I still carry that ammunition. There are people who are afraid of old ammunition, but in reality, it’s extremely stable. You can put it in on a shelf and shoot it 75 years later with no problems, if you can still hold a gun. It’s common to buy military surplus ammunition which is decades old.

I suppose you have to be concerned if you walk around in wet clothes a lot, but that isn’t me.

Yesterday, I fired a few rounds of my old ammunition. Zero issues. The gun itself is the weak link. It appears that lint from my holster and clothing have the potential to gum up the firing pin.

When you make your own ammunition, if you want to do it right and know what kind of velocity you’ll get, you need to know how much powder is in each casing. To do this, you need a good scale. It has to measure accurately within +/- 0.05 grains, and a grain is around 1/15 of a gram, so you’re shooting for about a 1/150-gram interval. That’s between 6 and 7 milligrams, isn’t it? Check my math.

Precision isn’t very important for moderate loads, but when you start going for more velocity, you risk blowing up cases, so you need to be more precise.

I had a Lyman digital scale, and I learned that it couldn’t be trusted. I bought a second digital scale, and I found out the resolution was 100% too big. Now I have an old RCBS beam scale. Can I trust it? Sort of. I use check weights to set it, but I don’t know how good the check weights are. I ordered better ones. I think what I have is fine, however. I’ll find out after the new weights arrive.

I got around the problem with the first digital scale by weighing two charges at once and dividing by two. I figured the powder measure was pretty consistent, and I had reasonable faith in the digital scale. I started getting 24.0-grain double charges, and I wanted 12.0 grains per cartridge, so things looked great. I made several test rounds, and they came in between 1200 and 1250 fps. Perfect.

Then I let the process sit for a few days, and before starting up again, I checked the powder measure on the beam scale. I got 11.8 grains. I guessed I had weighed the successful rounds incorrectly and that the 11.8-grain figure was accurate. I had to find out. I didn’t want to adjust the powder measure, use 12.0 rounds, and end up with 1300 fps. I made some 11.8-grain test rounds and fired them. I got velocities in the area of 1100 fps. Terrible.

Somehow, the powder measure had started throwing 11.8-grain charges, and I had to start calibrating it all over again.

On the up side, it looks like my digital scale was right. I checked some new double charges, and I got 23.6 grains if memory serves.

Why would the powder measure shift? No idea.

The check weights aren’t slated to arrive until Tuesday, so it would be stupid to go ahead and make defensive ammunition before they arrive. What do I do?

I think it’s time to crank out .45 target ammunition. I don’t really care if I know how much powder is in a target round, as long as I know the amount is safe. I have a bunch of old .45 brass and a fresh box of lead bullets.

After I typed the word “bullets,” I had to go take care of a tax matter, and while I was working on it, I heard and felt a loud thump. It was as though a truck had hit the house. I went outside and saw that the big oak in my parking circle had lost a fork. It was lying across the driveway. Had to go out, cut it up, and move it. It’s a beautiful day for working outside. It’s warm, but it’s dry, and there is a good breeze. While I was at it, I went to the pasture and moved some tree chunks from Hurricane Irma so the cattle wouldn’t have to keep walking around them.

I’m glad the oak lost a big branch, because the oak needs to be cut, and this will make it easier. A tree cutter quoted me $1000, which didn’t include hauling the wood. That’s insane. It’s a 30-minute job for him. For $500, I would have taken his offer, but $1000 is not going to work.

The smaller the tree is, the easier it will be for me to cut it myself. I hope more of it falls.

The tree is leaning, and the danger is that it will “barber chair” or split before it falls. If that happens, a part that splits off can swing around and kill me. I have read that you can prevent this by putting chains around the trunk. If it can’t split, you can’t have a barber chair.

To get back to shooting, I have to do something with the ammo I’m creating. I have very few factory-made ammunition boxes. When I used to go to gun ranges, I took cardboard ammo boxes out of the trash cans. They work pretty well, but they don’t last forever, and they fall open if you’re not careful. And the only range I go to is in my yard.

I decided to get some Harbor Freight ammo cans. These are sturdy plastic hinged cans. Like miniature plastic versions of the steel military cans, sort of. My plan is to throw ammo into them for storage, and when I want to shoot, I’ll move it to small plastic boxes with grids inside them. These boxes are made by a company called MTM. I already have some.

When I’m shooting, I like to know how many rounds I’ve used, and I don’t like to count. A box with a grid inside it will do the counting for me, and it will be lighter than a Harbor Freight box with hundreds of cartridges in it.

I’m getting a new chronograph. The Chrony F-1 I have now works fine, and it was a good choice when I only shot a few times a year. Now that I shoot more, it’s a drag. It has a display which attaches via an 18-foot cable. Attaching that to the chronograph and settling it firmly in the utility cart is a pain. I don’t like having to suspend the cable over old cow piles. The chronograph stores data, but it has some kind of primitive 1980’s-style interface for getting the data out. I don’t even know how it works. When I read about it, it was so unappealing, I decided I didn’t care to learn the details.

With my old chronograph, I had to shoot, stop, enter a number into my phone, shoot again, and so on. I’m all done with that.

Also, the company that makes the Chrony F-1 has an extremely backward website. They don’t have an online shopping cart. You have to email orders. On top of that, it looks like they don’t respond. I sent an order for parts the other day, and I haven’t heard a word. There is no conceivable excuse for doing business that way in 2020.

The chronograph has light diffusers which are held on by steel rods, and I shot one of the steel rods because I was twisting and contorting myself so I could shoot at a lower height. If you lose your steel rods, don’t buy new ones. Get some wooden ones. The diameter is 5/32″. The length is 18″. You can also order 5/32″ drill rod from Zoro Tools, which is what I have done. No idea whether the Chrony people are going to send anything.

I’m getting a newer model from a company called Competition Electronics. It has a bluetooth connection, and there is a phone app. You shoot as fast as you want, and the machine sends the velocities to your phone. I believe the app gives averages and standard deviations. Not sure. Anyway, it will be a big improvement. I should be able to use a Fire tablet instead of the phone.

I had been putting the Chrony on the same cheap tripod I use for cameras. That will not be necessary any more. I got myself an Amazon Basics tripod. Not having to remove my camera and attach the chronograph will speed things up, and it will certainly make it easier to shoot bullets and footage simultaneously.

It’s funny that we still say “footage” now that there are no feet involved in video.

I suppose it’s too late to drive to Harbor Freight. Gives me something to look forward to tomorrow.

    Thanks for the heads up on the small MTM boxes.
    Off to Cabella’s tomorrow.
