I hunted pheasants this year with a guy who shot a 28 bore Bespoke shotgun of some sort of British lineage. He shot RST 1oz, # 7 1/2 shot pigeon loads traveling at about 1300fps. That 28 was an absolute HAMMER on pheasants, and was hotter than the 20ga loads I was using. I was shooting 1oz of #5's at about 1220 fps. We couldnt tell a damn bit of difference between the two. 28 bores rock!!!!
