Has anyone tried this? Results? Charge weight? I'll soon be doing load development for a new barrel. Starting with 160 gr TSX FB. Barnes lists N165 as the most accurate powder. I note that load density is around 80-84%.

I've read some reports recently that shooters are getting good results with TSX's .050 or more off the lands. You?

I tried it with 150 gr. bullets and got 3072 FPS, which I consider very slow..67 grs. was absolute max. I found many powders that were better. The old standbys like IMR-4350 and 4831 got me almost 3300 FPS, as did RL-22 and 25..
