More than weight, fit is critical for any shotgun, and barrel length in lighter guns is almost as critical as well (at least for me). My Dickenson has adult dimensions and 28-inch tubes (& i'm thinking 30 would be even better). I'd love to see a discussion on sub-gage guns here, with the advantages and disadvantages laid out very clearly. I'm a big 12 bore fan because of its lethality, anything less IMHO is a compromise on that lethality but....weight (when carried all day) is a significant factor in upland performance by the hunter as well. For years now, I've found the 16 to be arguably the best compromise in weight vrs lethality in the uplands, but from using my little 28 for the last 2-years, I'm seeing good results there too. Ballistically, I see the 28 as being comparable to the 20, but with lots of weight advantages over the 20 (in both the guns and the weight of the ammo you carry).
