I took my recently acquired CZ 550 rechambered from WM to the Lott cartridge to the range today. When cycling cartridges through the action from the magazine, sometimes the Lott cartridge rims aren’t captured fully into the bolt face before the cartridge enters the chamber. The cartridge then hangs up on the side of the chamber before entering it? Doesn’t seem to happen when loading WM cartridges? Stiffer magazine follower spring needed? Thanks!
