I’ll defer on what is best for the big bears. However, in the 165 weight range, the 165 TTSX was designed specifically for the .300 Win Mag to put the ogive closer to the nose to optimize seating depth and typical magazine lengths.
I use it in my MRC .300 Win Mag with IMR 4831 0.010” off the lands and it holds 1” 3 shot groups at 200 yards and feeds flawlessly, which is something to consider for your purpose.
