7.7x58 jap ammo
Ok I have two cases here both stamped 7.7x58 jap graf, which I think is hornady, and the other is stamped 7.7x58 jap PPU which is priv. Now my question is why does the graf look way diff than the ppu? the neck and shoulder are completely diff... the brass length is the same but if you looked at them side by side you would say they look like completely diff rounds/caliber any suggestions why this is? They both shoot fine but I notice the PPU theres a little blow back from the round due ot the shorter neck and sligther shoulder. Again this isnt somebody necking down 30-06 or what ever , they both from factory stamped 7.7x58 jap but they sure dont look the same.
