They've Re-Designed them from, the early days of, the 1990's !The worst bullet failure I've ever experienced by far was a 140 Nosler Balistic tip in a 7mm-08 on a whitetail buck about 25 years ago.
They have, a MUCH thicker Jacket on them, now.
I'm looking at, running, the 150 NBT's in my .270 WSM,..
IF, the 140 Berger Classic's don't,.. "get it done" !
THEY would be, my next "choice" bullet.
Surprisingly, there are, lots of Happy Hunters using them.
