H322 for 223 AR loads

[iabowhunter]

I have an AR with a 16 inch 1 in 9 twist, chrome lined barrel. I've been reading on here how much you all love TAC powder, and I want to try it. My problem is I have a couple pounds of H322 left that I would like to burn through before I try TAC. Anyone reload with H322 for their AR?

I'll be shooting a 55 gr. Hornady SP bullet. I think that I was going to drop 23 grains of H322.....I say think because my load book is downstairs and I'm upstairs.

Thanks for any help.

H322 should be better than TAC for bullets =<60grs. It is not temperature sensitive like some of the other faster powders.

TAC is excellent for the heavier bullets and will work but is probably not ideal for the lighter bullets.
