This may not be of any help but I will offer it anyway. I bought a Model 70 Winchester chamber in 225 in the early "70s. It had a unertial target scope on it. It also had a bull barrel. It has been one of the best rifles I have shot in my life and has produced groups that I am proud of. I do not know if it will shoot cast, but the 225 will shoot jackets. Food for thought.
