Re: 338 250gr Sierra SBT
I realize you were asking about the SBT. I noticed no one had replied to your post which suggests that maybe no one on the site has experience with that specific bullet, I was suggesting the SMK as an alternative.
I used to live and hunt in the Pinedale area of Wyoming, so I understand about the bears, I want lead not bear spray too. However, I think you sell the SMK short. I have blown through both shoulders of a bull at almost 700 yards with one. Yes, the SMK is a fragile bullet, but keep in mind it is still 250 grains. That is a big chunk of lead and at the close range a threatening bear would be shot at would be quite devastating.
I'm not trying to talk you into something, or start an argument on the usefulness of SMKs for hunting. (that subject has been beat to death on this site) I was just trying to offer my experience with alternatives.
Another good one to consider might be the new Cutting Edge bullets.
