Normally or generally speaking I think most CVA owners can find one Powerbelt that loads and shoots very well out of their rifles. I have a CVA Staghorn Magnum .50 caliber. 90 grains of Pyrodex RS and a 245 grain powerbelt and I could shoot bulls eyes all day with the thing. It for some reason loves that combination. It also shoots the 300 grain XTP very well, and sence they are much more cost effect and I am a cheap so and so.. I shoot them.
