That's fine for double guns, which is the main thrust of the discussions here, but I just bought a 1912 20 gauge mfg. in 1916- 2&1/2" chambers, 25: mod. choke solid rib and the only one of my 11 Model 12's with a straight hand buttstock- so far anyways. So, will test fire it with some factory new AA skeet loads and see- my guess it, they will hang up at the front radius of the ejection port- so, if that is the case, I'll order 2&1/2" 20 target loads from RST. I would vote for Billary before I would alter any of my Winchesters--gospel truth lads. RWTF
