Sweet! Definitely a Collector’s Item, now. I’d rather use a 12ga on ‘em, w/ .00 buck.
A 2 3/4” 12 gauge 00 Buck contains 9 .33 caliber pellets. A 2 3/4” 16 gauge 1 Buck contains 12 .30 caliber pellets.
That load was highly favored for deer hunting in brush down south for many years.
It’s what I keep in my Winchester Model 12 for the home.
