Well I took the Winchester out today. I had an ammo can full of everything from old S&B 00 Buck to light bird loads and high brass 4s along with a couple hand fulls of mixed slugs. I also brought several boxes of new Super X 4s and 6s and two boxes of Remington slugs. It ate the hell out of all of it without a single malfunction other than two of the 15 year old low recoil 00 rounds didn't have the guts to re-cock, but they did eject and load. Patterned well and grouped slugs about baseball size or smaller at 60 yards, dead on wind wise but shot the slugs about 5" high.
Overall I'm very pleased
