An excellent choice, the 54 caliber PRB has the best ballistics of PRB's and is a drop them on the spot with the right hit and a decent load. It is more effective within its proper range than most sabot loads as far as deer are concerned. I load my 1-48 with 110 gr of RS my 1-66 with 120 grains of RS and my 1-80 with 130 grains of RS of course these are very strong guns and these loads are with in the recommended max.
