27.0 grains of TAC really shoots great in my new upper. I think the barrel is breaking in nicely [ATTACH=CONFIG]15820[/ATTACH]

Great group. Assuming that is at 100 yards? I'm still searching for that tight of a group with reloading and much more expensive barrels.

Yes, 100 yards. Thanks guys. Interestingly enough, at 26.5 grains the group was 1.1" at 26.0 it was .777".
