I used to shoot a couple of different loadings in 357, for silhouette, using a 195-200 gn swc or rnfp slug. 5.5 gns of W231 pushes that slug to about 1050 - nice load; 12.2 of IMR 4227 gets you to about 1000, so would 10.5 of 2400.
The 200 gn slug has enough 'carry' to knock the target over without driving it back into the berm and those loadings are easy enough to shoot from a revolver, so they should shoot nicely (easily, I should say) from a rifle. Mikey.
