I don't have any experience with the SST's, but would bet they would do just fine with in the low end velocity envelope on black bear. I would call Hornady as ask a tech on what that envelope is. Then to throw alil caution in there, add a 100 fps to what they tell you. My guess they should perform about the same as NBT's which are good down to 17-1800fps. In the 30-40, I suspect this will give the 165 SST more range than likely needed. If you are hunting close range out of blind, I have no doubt they'll work. Spot and stalk scenario in more open terrain, well with out knowing more detail, i suspect you can push 200 yds pretty hard, and maybe more.
