ouch... that makes it tricky for 28 gauge shooters. Is this for dove shooting? If waterfowl, then it isn't the farmers making the rules. Anyhow, Winchester and Federal make 28 gauge steel loads in 7.5 and 6 size. It's hard to find. I got a case of Winchester #6 from LeBaron in Quebec. It's ok for close and small ducks, but I had to get bismuth re-loads from a friend for serious duck shooting with my 28.
