For deer any 130gr bullet will work nicely I prefer the130 NBT under H4831. For larger 150NPunder H4831 is what i have used. Though I'd be inclined to try a 130gr Barnes TSX under one of the 4831's or RL19 if elk or moose are in the picture. I use the 140TSX in my 7mm rem mag it works awesome on elk and moose.
