223 77 TMK Non crunchy temp stable powder?

[kit.critchlow]

After I get my barrel back from Kampfeld, I’m going to do some tests with powders. I’ve got Tac, Benchmark, StaBall Match, StaBall 6.5, N150, Power Pro 2000-MR, and TS15.5. I’ve played with some of these before, but not in my current barrel. 2000-MR is supposed to give really good velocity

Did you ever do the powder tests? Of varget, staball match and power pro 2000, power pro provides 100fps more velocity for 75-80 bullets in my 20" 8 twist, 223 rifles. Also, not compressed or barely compressed. By far the best powder I've tested.

I would like to hear more results.

I haven’t been able to test everything yet. (Been wrapped up in a building project for months).

I did test StaBall Match, PP 2000-MR, and N150 with 77 TMK and 75 ELD. These are out of my 18” barrel with virgin Starline 5.56 brass. All of these groups are powder ladders too!
