Hello everyone ! I am tweaking a friend of mine's Vepr sporter rifle (.308). I noticed upon ejection that each case had a dent about mid way down. He had given me some South African ammo so I shot those first to get the scope as close to the target dot as possible. My plans were to finish with my handload 168 gr Federal GMM clone. I fired two of those and the cartridges dented in also. I ceased because I did not want to ruin my good brass. This is the Vepr with the RPK reciever. Does anyone know of such a problem existing ? Does any of the readership own one of these rifles ? Thanks, sure would appreciate any help on this one.
