I've never sectioned the 6.5 120 NBT, but have many of the other Noslers. I'd just read that it had a little more jacket. I've found accuracy in the 2850-2900 range and never worried about the bullet coming apart at that velocity.

I've yet to have a Nosler come apart that I'm aware of and I've shot a bunch of 40's in an 8" twist 223, including the Varmageddon. My 223 RAR Predator loves them at 3800fps...

I enjoy handguns and I really like shotguns,...but I love rifles!
