RE: 12 gauge 2 & 3/4", 3" & 3 & 1/2" Question
For years I hunted with my Browning 12ga upland special (2 3/4) over and under, mostly after grouse and woodcock.
But the last two seasons I liked my new (3 1/2) benelli super eagle so much that I've been using it for the same upland hunting, and shoot the same 2 3/4 Federal #8 game loads without compromise.
