interesting. ive only ever seen them boxer primed.
sort of off topic but I saw a guy on youtube once that was reloading milsurp steel cases by tightening the decapping pin enough that it would punch a hole in between the 2 small holes of the berdan primer.i think t was Czech 7.62x39
that would damage the decapping pin or damage the case i suspect. i tried it with the aluminum (to push the decapping pin up, lee set of dies) and the decapping pin went into one of the 2 holes and bend the anvil.
decapping with water didn't take to long, but i will not be reloading them again, to much work. if i had a small primer pocket reamer, i would have drilled out the anvil and use standard primers.
Alunmium cases should not be reloaded. That is why they are berdan primed. Just because you can do it doesn't mean you should.
i know, but what's life without risk?!
Are they actually berden primed or are they just multiple flash hole boxer primed to discourage reloading? This was the impression I was under. (talking the modern NA alum cases) I've never actually looked at them, just throw them back on the ground when I find them.
yes they are properly berdan primed accept they use standard size primers so you can do what i did and remove the anvil from the primer and use that. well i guess i can't say that until i fire them, but i see no reason why it wouldn't work, they had the same resistance when seating normal primers.
Does the aluminum case have an " N R" stamped on it anywhere on the head stamp?
If so it should not be reloaded,
All my CCI aluminum cased ammo is Non-reloadable.
yes its does have NR, and while it says that, it's mainly a legality thing. it doesn't last near as long though because of how aluminum reacts compared to brass.
here are some pictures,
i found 4x 38spl cases and was able to reload them 4 times before the cases started to split, and they only split when i went to bell the case mouth, not when fired. with the 9mm and 45acp all that seems to happen is the primer pocket loosens to the point that the primer will fall out.
