I'd leave it Mod/Full and shoot RST's 1 1/4 oz. of hard 5's at wary roosters. They pattern well.
Yeah. That RST load is about as close as you can come to the old Win AA Super Pigeon these days. Everyone seems to think they need more velocity. McIntosh, Brister and Hill all had good things to say about the Super Pigeon formula: 1 1/4 oz, 3 1/4 DE--1220 fps. Threw great patterns. Winchester never offered those in any shot sizes larger than 6, so if you like 5's, the RST's are the way to go. They pattern better than the old Super X formula (1330 fps), although there's not a significant difference--other than in recoil. And both of those pattern better than the current "premium" lead pheasant loads at 1500 fps.
