I tried the 777, fff in the CVA. I loaded 25 grains behind a Hornady .310 swaged ball, and a pre-lubed .10 patch. It goes off right now, and shoots around an inch at 25 yards. Shots at small objects, a red brick, at 50 yards have all found the mark. I will keep working on the load. If it gets any better than it is, it will be more than enough. I will shoot a couple of woodchucks with it this spring. Maybe a turkey in the fall. Then squirrels. I am thinking of a cap and ball revolver as a companion gun. Maybe a Colt copy in .32. I am not giving up my cartridge guns just yet, but this is lots of fun. Shotgunner
