SST....I've got 220 sighted for 2 inches high at 100. Both loads shoot well. We've killed deer with both the full load and Lite. The lite definitely has less recoil and is basically all the same out to 150. I prefer to use it vs. the smokeless one shot. I think I do shoot the XTP bullet in smokeless because I got 4 boxes with my gun.
SST has put down 5 bucks 132-178 lbs dressed from 25-75 yards. 2 dropped like an anvil, 2 ran up to 60 yards with no hearts, and one spine shot needed a second round but by golly we got him.
I started shooting it because it was the only brand in stock at Academy. I found the lite loads at a great little hunting store in Bolivar and I have since been able to find plenty in stock at Cabelas, Bass Pro, and Field and Stream. I also got 5 boxes from Midway last fall.
I do need to shoot soon. It was unusual for my son to not hit a buck in the boiler room. I also picked up a second compact 220. I may put it in a Boyd's thumbhole now kids getting older. I'm 6 ft but I really have not had any problem shooting the compact version.
