I am starting to get into skeet shooting and all I have is my 870 + 28" rib barrel. I see a lot of 20ga, some 16ga and few 28ga shotguns out on the field. I shoot last weekend ~80rds of 12ga target loads and my shoulder was a bit tender. Are there any lighter, but effective 12ga loads out there? I loaded up 2 3/4" hulls with 1 1/8oz #9, 20grs Unique and Fiocchi primers. The factory loads were Winchester Super Target 2 3/4" 1 1/8oz #7.5. These have a much stronger recoil than the 20ga my buddy let me shoot. I'm not ready to purchase another shotgun so I'd like to keep using my 870. Eventually I'll get an O/U, but I think I need to improve my skills first then worry about another shotgun.
