I used 150gr 30cal NBT (308 Win) not long after they came out,1 box of 50. Stopped using them as they were too fragile. Jacket separated from core nearly every time on deer, pigs and sometimes on goats.Pain in the arse to find jacket with knuckles when punching skin off deer. Went back to Speer SP and Remington Corelokt, no more dramas. Might give NBT another try though after reading this post.
