BWalker, I am wondering if indeed there is a lead risk with the NBT. Can't see that being an issue since all the lead is encapsulated in the jacket and no exposed tip.
I personally think the NAB and clones is one of the best do all bullets made. That said, I am running 100 gr TTSX'S in my .257 bee this year because they give me a little better accuracy than NABS.
Perhaps Barnes would be doing everyone a favor if they would open up the tip in .30 and under bullets?
