Is your gun chambered for 3" 28's now? Didn't think so. Why not just buy a 6# or less English double 12ga. and shoot 2" or 2 1/2 " shells, with 2 3/4 drams eq. , move on up to up 2 3/4 " short mags when needed since your going to need another gun anyway, and recoil isn't an issue for you. Better pattern density, and all loads from 3/4 ounce spreaders to 1 1/2 ounce baby mags. 3"mag 28's may thrill you, but I have 6 28's 2 3/4" now, and I just wish there was a better variety of 2 3/4 " offerings in 28 ga. But I realize it's not the sexy pick, like a 3" load. I would also suggest that having loaded both "nice shot", and tungsten matrix, in 28 ga. You and your skills, excepted. I will guarantee you that in the hands of nearly all shooters, a 28ga. loaded with lead or unleaded shot is a major crippler of game unless shooting small birds, and picking your shots,which most nimrods can't or won't do on pheasants or ducks. I love 28's, I also shoot a lot of 20's, I'm hear to tell you that recoil will be an issue in a frame scaled 20, or 28, thin walled, double, weighing 5.25 #'s. Pleasant day and good luck to you, I won't change your mind, and you won't change mine, I'll let the market tell them good or bad idea.
