Am considering having the QLA removed from my Omega to see if it will shoot conicals any better. Anyone have 1st hand experiece that this has helped? Cost involved? Can't see any downside other than the cost. It now shoots NE 460 grain conicals with a 8" group at 25 yards. Couldn't get any worse. It will shoot powerbelts OK with pyrodex and lower amounts of 777 (of course I get a crud ring with 777).
