Sourdough,
Yeah, that's one of the first things I did. I am a big Barnes-X fan and being my 30-06ai will push the triple shocks at 2580fps (5 feet from the muzzle) with 52g of IMR4064, I feel the performance would be adequate. I contacted Barnes and fully explained my situation and was told I can expect the triple shocks to properly expand at velocities as low as 1650. That would put my effective killing range somewhere in the 300 yard range (way more than I would attempt a shot). I limit my handgun range to no more than 200 yards. The Sierra bullets, I was told, would be effective down to 1800fps. I thought that was kind of strange. Anyway, I feel comfortable with the TSX leaving the barrel at 2580fps to be effective on a black bear out to 200 yards.
Thanks again guys - you really helped me out a lot!
