I killed several deer with the “original box” 270 and 7mm 140 btips out of the 270 win and 280 Rem. MV was 2900-3000 fps depending on rifle and load and they worked very well. The bullets exited on deer I shot with no signs of blow up. The only 140 Btip I can remember not exiting was a 140 combined technology in a Win factory load out of a 280 Encore. I borrowed the rifle from a buddy on an out od state trip. The barrel was long - 28” I think so additional velocity may have played a role in not exiting, but the deer dropped at shot anyway

I know I still have some original 270 140s and would have no qualms using them on any deer hunt at least
