Thanks for the input, Gentlemen. There were some 130 Speer BTs sitting lonesome on my shelf. Decided to give them a shot in a 280. They make small groups at about 3080fps, but haven't tried them on deer. I have no doubt they would work fine for broadside lung shots. Just wondering about their performance at fairly close range with a high shoulder shot. Often need to do that to anchor them on the spot. Guess I''ll try 'em on hogs first and see if the don't bounce off.
