Barnes bullet question

[Bounty Hunter]

question for all of the people who have killed game with Barnes TSX bullets. it has been my experience with traditional leadcore bullets(BONDED OR NOT) that you can get them too fast and from a killing perspective do yourself a disservice ie; having to track etc.-- slow it down a little and you don't have that problem. now i have two loads for the 120grn. TSX that shoot equally well one @3200fps. the other@3000fps..(actually chronographed). naturally i would like to shoot the 3200' load but don't want to create a problem either. i have read many many threads and this looks like a great hunting bullet. i am not real concerned about the 100yd. shot cause we have the luxury of hunting out of box blinds w/good rests, so neck shots are available. i am talking about the 250-350 yd shot. i won't shoot farther than that, just wait for another day(patience is a virtue). has anyone been able to make them blow up or do they pretty well stay together @ all velocities?

thanks
