Purchased this new and the original barrel shot 1 oz slugs well. After shooting in a 3 gun match I wasn't impressed with the factory sights on the barrel. I then sent it to Vang Comp Systems to have a new barrel and ghost sights installed with a Mesa Tactical shell holder. I"m now trying to find a proper slug to shoot with it. S&B suck. Low recoil slugs cause it to jam. I've sighted it in at 25 yards with Brenneke KO 1 oz slug and it's a nice tight group. When I shoot at 50 yards it seems to be about 8 inches or so high. I shot the 1187P off the bench and it should shoot at least a few inches high at 50 yards. Shooting the shotgun is not my forte'. Does anyone have any ideas of what type of slug I should be using?
