[QUOTE="MudRunner2005, post: 1450317, member: 12995"] The 450 "magnum" primer has a thicker shell to prevent slam-fires. This is caused in semi and full autos when the bolt rams another round home, it hits the primer when seating the round into the chamber, and causes the round to fire if the primer has a thin shell, or is sticking out slightly proud compared to your other normal primer depths. Magnum small rifle primers don't always prevent this (if something is wrong with the gun itself), but for the most part it's just good practice to use CCI 450 primers in semi-auto rifles. [/QUOTE]
