Have you tried different ammo? Maybe PBA?Maybe dropping your scope on the floor then reinstalling?Might give you a challenge to work on.NO I'M NOT REALLY RECOMMENDING THIS folks.LOL
I have a Marauder .177.I had a Marauder .22.I have a TX MKIII.I sold the .22 because it was boringly accurate.The TX might be next.Hard to tell when you hit the target (unless you are using re-active targets).Same hole or very close.Boring.
