Try the 300 grain Federal factory loads. They are loaded with the 300 grain Speer hot cores. Dunno how many deer that I have flattened with them. No complaints. I have recovered one of them, and that was because I seen where it hit the hill on the other side of the deer. Shot one at 200 yards head on, and the bullet came out the other end. Am now loading 420 grain hardcast with a heavy charge of IMR 4198. Recoil is pretty stout, but if I run across a grizz in the hills with an attitude I know that I can stop it quick.
