With my CVA Optima, I shoot 85 grains of loose pyrodex with a 295 grain powerbelt hollow point. I'm not needing to shoot over a hundred yards where I hunt so I dont need any heavy hitting magnum loads. If you use loose powder, you wont have to be stuck with a certain charge amount. Usually, shooting this load feels about like shooting a 20 gauge with squirrel shot. Start at around 75 grains with a 3 shot grouping and increase it by 5 grains until you get a good pattern.
