hi every one this is my first time on here.Been airgunning for a few years now and decided to get myself the r10mk2 .22.Problem is i just cant seem to get it to group at 25 yards,tryed 3 different scopes and still no luck,even 3 different types of pellets the best pellet being premiers.Checked on chrono heres the velocity result after 10 shots 572,584,577,594,586,569,578,588,592,589.my groupings were 60mm from a rest has anybody else had this problem with the mk2.
