You should be able to get 1500 or possibly 1600 fps with a conical in that 45 and you should be able to get a considerably more heavy bullet at that velocity. I think you could easily get a 400 grain pill in that rifle to do 1600 fps. That would be considerably more devastaing on game over a 200 grain pill in a sabot(IMO).

I think the conical bullet is the real advantage of the 45 caliber MZ.

I always believed the 45 caliber MZ should approach 45/70 ballistics. Why not??

Have you measured the bore in your rifle?? Tom.
