Kevin, if you're concerned about recoil, try dropping you bullet weight to around 300-325 grain. In the BM you can go down even further in weight if you wish, Lymans 255 gr 452490 comes to mind, it should feed pretty slickly in a rifle. IIRC, you're shooting a Savage aren't you? If so you can experiment with practically any .452 pistol bullet. My SOCOMs in the shop right now, but my utility bullet for it is the RCBS 300 gr .458 rifle bullet, I'm still searching for a reasonably priced SAECO mould for the bullet I really want #017. I'd only use the heavy bullets if you're running a suppressor, or at longer ranges. BTW, my first cast bullet deer was shot with RCBS 325 gr bullet at really moderate 15-1600 fps, at under 50 yards and I have yet to see another deer as impressed with a bullet as that particular white tail was. It was a side shot, and penetration was complete, as expected.
