With my first .458 2", I used a light load with a 320gr. cast FN bullet for the first bear - driven at about 1,450fps, then raised the ante` to about 2,000fps for the second bear. The results were the same - struck behind the front leg, centering the lungs into the off shoulder, both bears waddled about 20feet and died.

For longer range shooting, you might want to boost it a bit. The Baikal's ceiling is around 31,000PSI, which will allow well over 2,000fps with 300gr. jacketed - the Nosler Partition comes to mind. Guys have found it to be a super deer and black bear bullet - penetration way over what a 300 normally would produce.

For Elk and Moose, the 350 Speer with top-end loads should work well. That's the one that's too long for Marlins & has a 1/16" thick jacket designed for over 1,900fps MV.

Of course the Hornady 350RN & newer FN are also VERY good bullets for all NA game.
