Yeah they have a QLA but do not have the problems the omega has. They shoot conicals with out any problems. My winchester with 90gns pyro rs and 385gn great plains conical got 2" groups @ 100yards. I dont have a shooting rest so its either off a tree limb or the 4 wheeler seat or even a fence line. I think im going to change to shooting off a fence line, ive been getting better accuracy.
