Not exactly what youre looking for, but some good info here regarding heavy tac loads, if no one else chimes in with what you want.

Face shooting buddies of mine swear by 70gr Barnes bullets.

Thank you for the data !
I was looking for some real world data from Reloader's.
It looks to be around 26.0 of TAC

Western lists 25.6 as max for the Barnes 70 TSX in their 5.56 load data and shows a tested pressure of 61,273psi as an already compressed load (coal 2.260). Adding another almost half grain may not be prudent. Just something to think about.

All manual after 1967 have been lawyered diluted and watered down……I just use it as a guideline not concrete !

Edit: Barnes lists a max load of 26.0. I’ll have access to my hard copy manuals this weekend, hopefully. I’ll take a look at some other data. The powder manufacturer lists a max of 25.6.

As far as real world, I’ve never reloaded that projectile, but I’ve shot a good bit of cartridges with it, and its very good. What are you trying to accomplish with it?

Caribou load !
Don’t worry I want go past 26.0
I will use LC brass and WSR primers.
