Use it in my Norc M4 behind a ARMSCOR 62gr FMJ. works splendidly and burns surprisingly clean. Seems like the burn rate is between H322 and H335.
Because it is an older gen ball powder, temp sensitivity should be expected.
It would not be my choice for heavier bullets or when peak accuracy is demanded.
however, to make bulk blasting ammo, love it. I am loading on a progressive and the powder flows like water.
I would consider this for testing if I was in gopher country and was loading up lighter varmint slugs.
