You either need to send that scope in or take the time to get your reticle focused(not saying you didn't). mine is good at all mag ranges.I have a 3-24 x52 March F.I like all features of scope,but past 20 it is not clear and I get no use above that.The paralax is very picky also on the 20+.I have a Leo Mark 5,5-25x56 and it is much clearer at 20 and up.I could see twist in barbwire at 440 yard and it was just line in March,that cost much more money.Like the weight of the March for packing
