Started at 39.5gn in 015 grain jumps: 41gn was kicking harder than the factory ammo I put through it in Az & was cratering around firing pin. Chamber a little tight?

Beats me (in this set up at least) how you would go to 43gn AR2209.

what speeds are you getting? Tight chamber will get the same speed with less powder
