CPA

[Steve Anderson]

So, my friend bought a CPA chambered in 40-82. This a cartridge neither of us know much about ( read, nothing ). Now he's looking for brass and can't get enough info to figure out what to buy. As I understand, 45-90 can just be sized down and it works fine. He has found 40-82 Silhouette brass at Buffalo Arms, will that work? I have no idea just what Silhouette brass means and apparently Buffalo Arms told him it was thicker. That leaves the definition just a little vague. Any help would be appreciated. Thanks, Steve.
