I think the rotor design was purely based on the length needed. Now if I can alter a 284 rotor to work in place of the 243 (using existing parts in the rifle) it may work as the 450 BM while based on the 284 case is not nearly as long.
Mike if it can be drilled to fit on a spindle I think the length change wold be easy, could I just use the spring in the rifle?
Jeff if I had some ammo I would send you a few to try with that 375 rotor.
