Well thanks for the help. I tried winchester, winchester winelte, breneke K.O., and federal. All in 2 3/4". By far the winlite was the best slug through that barrel. I shot 5 times with all slugs. Using the winlite 4 shots were less than 3 inches from the centre of the target at 40 yards. I went back to 60 with the 5th shot and was 4 inches low but on centre. My son will be shooting thoes for deer season. They did have a noticeably less recoil thatn the rest of the slugs.
