TAC seems to work amazing in the 223 heavier pills (69+) and very solid in 308 Mid size pills ( 150-168) so I anticipate good results for you. Another powder that has shown really solid results is AR-Comp. I over looked this powder for a while now and got a few lbs of it on clearance from a local dealer who was WAY over stocked ( like $18 per lb!) and man am I pleased. Not only is it working well in my 308 loads...it has great promise in both 223 and Grendel as well. TAC still has a place on my shelf....but Alliant is really making a case for itself lately with all the powders I have tried from them.
