Matt-you're forgetting that the rifles you speak of are centerfire, in which the primer is directly in middle. The rimfire he's asking about is primed around the outside rim of the case.
good catch on that stalking bear was wondering if anyone would catch onto the fact that spitzers are trouble for CENTERFIRE tube fed gun. by the way during ww2 remington did produce jacketed 22lr ammo for the military to meet the hauge convention regulation against expanding bullet use in combat, so it was developed as a fmj load. was refered to in 2 designations as the m24 and m42 loadings. where is all this going you ask? i am a collector of oddball 22 ammo and was hoping someone was willing to sell me either individual or full box of this ammo they may have laying around. if you have some you dont want pm me please. thats all folks
