Are 20s still considered sub gauges? I know they are for sporting clays. I used to shoot clays a lot, but not as much lately since I started doing cowboy 10 years ago. I always liked shooting 20s best, not because of any recoil issues (a 7/8 or 1oz load in a 12 actually shoots easier than a small bore because of the lower pressure and generally heavier guns) but I just like 20 bore. 28s are an absolute delight to shoot and hit hard, far better than most would think! I don't know why the prices have gone astronomical lately, but I think smallbores have always held a certain cachet. I'd say perhaps loading component costs, certainly not factory ammo, but you can assemble spectacular performing 7/8 oz 12 guage loads so not much diff there. I use them in my 6 1/3 pound Gold Label and don't find much difference there from a 20 except that they are doing nearly 1400fps vs 1175. Much smash'em!
