I tried a few boxes of the 1 1/16 loads in my 28's but they kicked harder and didn't pattern nearly as well as the 15/16 loads. I have 6 cases of the 15/16 left and shoot them happily for SDak sharptail, huns and desert quail in NM. They tend to shoot very tight groups so I open the chokes a bit depending on the quarry. Not sure if the 15/16 are available but you might try them.
