I also own a remington 1100 (12 and 20) so i have to ask, is it a 2 3/4" or 3" chamber?
if its a 3 " any turkey load will be fine, but if its a 2 3/4" chamber you might have trouble finding turkey loads. I recommend using Remington pheasant loads and I have killed a few and never wounded any with them. but any pheasant load will work.
