Does your gun have the 14 inch barrel? If you have the ten inch barrel trade it for the longer tube. I presently use 150 grain Speer flat noses on top of a max charge of 3031. I used the 130 Hornady soft point and the Speer hollow point also for many years when I lived in Wyoming. These I used IMR 4198 behind and the Hornady bullet had a real tendency to tumble fired from my 1 in 14 inch twist barrel but it still was a quick killer of mule deer. If you like muzzle blast try H335.
