Today I was shooting 4 rounds of Grizzly 460 gr +P ammo with my Henry 45-70 Lever Action and the rifle had a hard time ejecting empty shells. Loading and shooting was smooth, but to eject each empty shell I had to pull the lever really hard and do it multiple times. Any other ammo that I shot with this rifle ejected with no issues. In fact, after shooting +P ammo, I shot 16 more rounds of regular factory ammo and did not have any issues. Interestingly, when I got this rifle new 6 month ago I shot few rounds of the same +P load and the rifle was ejecting better (just slight bump when pulling the lever) +P loads when it was new than now. Has anyone experienced this issue with +P loads?
