I use 7/8 oz RST 8 1/2's for both grouse and woodcock early in the season. Once the woodcock are gone, 1 oz 7 1/2's for grouse.
Pheasants: RST makes a very good pheasant load: 1 1/4 oz 5 or 6 @ 1200 fps, which is very close to the old 3 1/4 DE-1 1/4 oz pigeon load (which is hard to get in a quality shell these days, at least with shot any larger than 7 1/2). But most of the time, hunting them over pointing dogs, I use 1 1/16 oz Brit 6's--Gamebore Pure Gold--in the R barrel. L barrel, reload 1 1/8 oz American 6's at about 1150 fps, 7,000 psi.
