My CZ455 HATES the CCI Maxi-Mag 40gn JHP cartridges.
Lucky if I get 1 round in 10 feed into the chamber.
Tried all 3 magazines (2 poly and 1 steel), and they all do same.
Followed the CZ instruction for bending the rear mag-follower leg (instructions are for .22LR feed issues), but no improvement.
Frustrating that I'd bought a 200-round brick of the damn things, before realising they dont feed.
Finally part of the problem; a step/ridge formed in the copper projectile about 5mm in front of the case mouth, and it catches on the chamber during feeding.
Solution was to use either the Hornady Vmax ammo, or the CCI VNT ammo; both feed with zero problems, and seem to be giving me around 1.5" at 100 yards.
Some time I'll revisit the problem; looks like the cartridge isnt angled correctly when being stripped off the mag, but not sure adjusting the mag follower will be enough to solve it.
