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!

N540, 25 Grains, LC brass, CCI450, 77 TMK. loaded on one of the 650s that is still set up for my service rifle short range competition ammo.

Two years ago, after I chambered my 223 bolt gun, no load work was done, just cranked ammo on the Dillon, zeroed and dropped this WT at 240 yards.

It looks like there are a lot of possible powder choices available according to the previous replies.

There are two more that I'm surprised have not been mentioned:

I am getting identical velocities as IMI MK 262 Mod 1 while using Hodgdon CFE 223 and also with Alliant AR-Comp (although currently unavailable). Neither of these crunch at mag length with 77gr TMKs..
