I have an A5 Browning that dose not cycle. I have set the recoil spring spacer for light load (as per factory instructions), and have tried my cowboy loads and some heaver loads no luck. I also have a Stevens 720, that once it was set for light loads it will not shoot the cowboy but will shoot the field loads. The Browning has a poly choke w/ compensator. The field loads are 1 1/8 oz., should I try heavier.? I have done some research, and have seen some ways to compensate . Although what I have seen, I am not sure are safe. I am open to suggestions.
