I'm running H322 in all 3 of my 20Tac's (1 bolt gun and 2 AR's).
All the barrels are 1:11 twist.
I still have to do the load development on my shorter barrel (20") AR but the others have shown promise.

My long barrel AR is a White Oak Arms 24".
40 grain vmax coated in HBN seated .010" off the lands.
26.3 grains of H322 (this is extremely hot)
3915 fps and just over a 1/4" group.

My bolt gun is a Tikka T3 with a 22" Carbon Six barrel and Bell and Carlson Stock bedded.
40 grain vmax coated in HBN seated .007" off the lands.
26.9 grains of H322 (very hot as well)
3913 fps with a .24" group and a SD of 6.1

Early load development on the light barrel AR suggests that I need to be in the high 25's to low 26's of H322. More to come as the weather permits.
