I have a Remington 1100 Skeet which I bought used. It comes with 2 fixed choke barrels (skeet and full). I know loads like buckshot and slugs are out of the question but what about loads that fall in the middle? Like the other day my friend handed me some #6 shot bird hunting loads which I noticed kicked a noticeable amount harder than the target loads which I had been firing. So basically my question is that are the limited to what I can feed my 1100?
