Hornys 300 xtp are plenty of bullet for me. Pushed with H110, they penetrate and fly just fine. They are accurate from my 10" sbh at 100 yards. Have not retrieved one from any animals yet, but dug some up out of the sand after hitting plywood targets and they mushroomed out. Penetration wanted, go with some of those hard casts from various vendors. I just don'tsee a need for anything over 300 grains.
Question, most people encounter grizz when in Alaska, but how many have had to draw and shoot one? Most guides i read about pack a shotgun or a carbine. With all the talk about packing the big hurt for all these bears, they ought to be extinct!
