Further update...

Nosler doesn't list it online, but I got my hands on their manual and they do list a Big Game load with their 120 NBT.

It lines up with exactly what I'm finding:

They list:

48g at 3090
*50g at 3190 (*most accurate, and looks real close to what I'm seeing)
52g at 3262 (max)

I can generally push 120 TTSX's a little harder than 120 NBT's...

Anyone other than me a little me a little distracted at the prospect of an accurate 120 grain pill at 3200ish (maybe crowding 3300!) out of a 7--08 Montana/Faux Ti/Ti and the other great packages that can house it???!!!!!

I'd build a rifle around that.

I'm pretty fired up...grin.
