I shot my 220 grain dead centers today. I got them centered in at 50 yds. I was shooting off the hood of my truck and a rolled up blanket so accuracy obviously wasn't the best. I stayed with 100 grains of 777 and the 220 grain bullet. They flew quite a bit higher than the 300grain xtp's I was shooting. Hated to use all the bullets but glad its where it needs to be now. Any advice for sore shoulders. I hate sighting these things in. After 4-5 shots I start getting the flinches. Dang, these things kick. I'm 5'7" and 210#'s so its not my size, these things are a killer. Muzzleloader starts next week. I can't wait. Greg
