There is nothing at all wrong with the 338 with good 250 gr bullets.
I used that exact combo to kill a 7 1/2 foot interior Grizz in the Talkeetnas.
It took several hits and slid down the frozen slope.
No bullet trumps good shooting.
Love that hide photo Phil!
What did that toad square?
Here is my Kodiak.
10ft 1 square.
Always love your input Phil.
Few folks can discuss the big bears of Alaska with the level of knowledge that you posess.
