Is that a minimum, moderate or max load?
I've used TAC in the .223, .30-30 and .308 so far. In the .308 and .223 it seems to shoot best at or near the max charge Ramshot lists. In the .30-30 it didn't do well at all since even the max charge has a very mild pressure.
Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
