I just got off the phone with Jeff at RCC Brass. This is related to my earlier cryptic post about doing something that by many standards would be considered somewhere up on the stupidity scale.
For those of you who don't know RCC, they machine brass in all sorts of wonky (and not so wonky) calibers - he told me they're making shells for the 75mm gun of a Sherman... This is not stamped brass, it's machined out of solid brass rod, and done so to very tight tolerances. Anyway, I asked Jeff if he could make 300 PRC brass, since it's not on their web site, and he said that since it's got a SAAMI spec, they can make it for $5.65 a case. That's a lot per case, but then the brass isn't worked much during forming, so it lasts longer. Even if it only lasts 50% longer, you're getting it for the equivalent of just over $3.75/case. Still a lot, but then you're also getting cases that measure out at +/- .1 gr of water per case, according to Jeff, so very consistent.
I ordered 100 cases. I'm going to run extensive tests after I receive them. Unfortunately they are a little backed up and I have to wait about 8 weeks. As always, I'll post the results. I'm looking forward to tinkering with them...
It’s funny that you mention them. I ran across this for the first time when I saw the 375 terminator. Honestly it is a lot but the thought behind it is solid and the quality is supposed to be outstanding. If we did a group buy do you think the price would go down? If not I’d still be in.
I don’t know if you’ve thought about it but once the 300 Sherman magnum has a steeper shoulder would there be an issue fireforming?
