If I'm reading this drawing from the SAAMI web site correctly, the rim thickness of a .22LR cartridge should be 0.043, plus 0.000 minus 0.007, and the head space relief in the breech face or bolt should be 0.043 to 0.051.
Am I reading this correctly?
Reason I ask is because I've had an email exchange with someone at Winchester inquiring as to what the rim thickness is on their XT22 target ammo. Their reply was that their ammo rim thickness meets SAAMI specs of 0.043 to 0.051. I went a bit deeper into the next email I sent, basically telling them they were wrong, and maybe that is the reason my target pistol is slam firing with there ammo, they are making the rims too thick. They stopped replying after I said that.
So who is correct, Winchester or me?
