I purchased some russian .233 ammo a few years back at gun show in pittsburgh PA with "TCW AMMUNITION" printed on the front of the box. I reload rifle ammo and use primer inpection in judging pressures. These rounds pushed the primer indention outward into the firing pin hole of my rossi break open .233 and as a result I had to smack the barrel down to break open the action. My first thought was it was hot because it was designed to be used in gas powered semiauto rifles. Does anyone have any experience with this ammo? Any info why this ammo is Hot? Just how hot is it, and is it Dangerous?
