I think we all have one of these friends:
Until I realized I had too much. From there I moved to MTM crates and ammo can crates. The simple crates are just sealable boxes of different sizes. Good handles on the side, and they can hold a fair bit. I started storing bullets and other gear of that sort in them. There is one crate that is nothing but misc magazines, for example.
The other crates hold 4 or 5 ammo cans each. 4 50 cal cans or 5 30 cal cans. They have some for their plastic ammo cans and some for regular GI metal cans. I use both.
A few months ago, I found some 8 mm Mauser boxer primer cases. I picked up 125 for a good price. This is good. I can now make freedom delivery systems for the K98. A week or so ago, my Redding 8×57 mm dies showed up. I resized 10 cases, measured them, they don’t need to be trimmed. All good.
I started my research knowing that 8×57 didn’t take the same bullets as 30-06 or 7.62×51 NATO. No problem. In my research, I found what, I thought, was a great piece of interest. This was from my reloading sources, so it was good information.
7×57 mm cartridges use the same bullets as .303 British. This is wonderful! I have lots of .312 bullets.
I can’t find them. They are nowhere to be found. I started tearing the reloading room apart. The crates labeled “bullets” are at the bottom of the stacks. And when I got to them, I found 1000s of bullets. None of them .312.
I became more methodical. I started opening every can to check what was in them. On about the 15th can I open, a 50 cal can, I find it has the neat trays in it. It was at that point I remembered that I had put a number of bullets in those trays, to make it easy to find.
Sure enough, I find my Hornady SST .312 150gr bullets. This is wonderful. I weigh and measure the bullets. 150gr, 0.312, all good. I pull open my sources, yep, 7×57 takes .310-.312. Everything is going well.
I open up my reloading book, pick my powder, IMR 4895, start writing down my planned loads. I’m just about to prime the cases when I look at the bullets and the cases. Those necks look bigger than the bullets. I take a bullet, put it in the neck of the case and it falls in. That neck is larger than the bullet by an unreasonable amount.
Back to the books, 7×57 is 0.310-0.312… Whiskey-Tango-Foxtrot? The references are 7.92 mm by 57 mm. So, 0.312 does seem a little small.
Back to the books, 7×57 is still 0.310-0.312
DOH. No wonder I was rounding off the corners.
I want 8×57, not 7×57.
The Mauser is available in many calibers. 7.92 mm is expressed as 8 mm in the references. They also make a 7.62 by 57 called the 7×57 mm. I was looking up the wrong data.
Be careful out there.
