All I know is I have used my 300wsm with 180 gr TSX for elk, bear, deer, and antelope. I shot the deer at 75 yards almost end to end, ended up under the skin on the long shoulder, perfect expansion and mushroom, nose in the dirt almost instantly. The antelope was 327 yards, I hit the shoulder and you could see thru the animal, the bear was 138 yards thru both shoulders, perfect expansion recover on out side of bone under skin, perfect mushroom, and for my elk, he was 386 yards, my first shot was low and back, he only made it 100 yards and bedded giving me a quick finish up shot. The elk got real sick real quick and the bullet made up for my bad shot. Last year I used the new 80 TTSX out of a 257 weatherby and at 284 yards, bang, no flop, just dead antelope!
That said maybe others have had not so good luck with Barnes, but I have had great luck with them, I thin it is like anything else, if you have confidence in what your using it makes a big difference. I have been impressed with the trophy bonded bear claw and may try one soon.
On another note I used the 150gr GMX on both of my spring black bears and although the shots were close 25 and 20 yards the bullet killed them almost instantly and the wolf I shot at 200 yards dropped like a rock, all with a single shot 308.
My best performance on deer has been with BST out of a 270, 243 and 300 wsm
, took my first goat with a 243 wssm 85gr BST and he dropped in 2 steps. I hunted with a guy 2 years ago and he used the 180 gr BST which is built stronger for big game and at 100 yards his bull only went 50 yards, but not the round I would want for a strong quartering shot or long shot when I need to break shoulders. My wife shot her antelop with a 243 using the SST and I was not impressed.
I think the power points, corelocks, are good for deer and behind the shoulder shots on black bear at reasonable ranges, but I will take my TTSX for Elk/spot and stalk bear or big mule deer.
