The 30m1 is a neat revolver round, although really LOUD. There is reloading data available for revolvers but you can also use the data for carbines, just recognize that you'll lose about 250-300 fps in a revolver due to both shorter barrel and the cylinder gap, but they still get right out there. The Speer 110 "Varminter" flat nose hollow point is a fine game bullet, I've taken a couple of deer with that bullet in the m1 carbine.
