My .243 Win is refusing to shoot the 80 TTSX, simply refusing, so I changed gears. I have a couple of boxes of 95gr NBT so I figured I would give them a whirl. It looks as if it's going to work out.

45.5grs IMR-4350 is right @ 3200fps from mine with the 80 TTSX with very small and very consistent groups. I just seated mine to the center of the top groove and kept adding powder.
I always size my belted cases like nonbelted cases, I just bump the shoulders back .0015-.002" and I get 12+ loadings from them.
Following the directions they send with the dies is a good way to overwork your brass and shorten case life.
Most of my stuff is limited by mag length but I typically start at .005" off but most of my stuff usually shoots best from .025" - way the hell off " the lands.
I don't crimp semi-auto rifles either.
I loaded a round for my AR and fed it from the mag 10 times and then checked OAL and concentricity and both were the same as when I loaded it.
