What brass does Freedom use, KR? I wouldn't be afraid to reload it if its military brass because it's most likely once fired.
You can reuse brass over and over in most cases.
I see my local Walmart has the Federal .223 100 rd. value pack 55 gr. for $34.97. Seems like a decent price per round for brass.
I have had good luck with those as well.
Tula, Wolf Polyformance, Monarch, or my reloads are all I shoot.
The ammo snobs will fall off their tall horses to condemn steel case .223 but I've had good luck with TulAmmo. I only used it because one of the only places to shoot near here doesn't allow brass pick up so all I shot was rimfire and steel .223. I was able to hit 8-10" gong from 190 yards 8 times in a row with open sights with Tul. Otherwise I generally load my own.
