Whoa! That would be a big problem! Contact Athlon for return label. They’ll take care of you quickly. That’s a lot to be off... have you confirmed your distance with a tape measure?
Mine was right on all the way up to +10 Mils elevation and points in between.
Thanks everyone. This was my first go around with Athlon. The first thing I always do with a new scope is a tall target test and this put a bad taste in my mouth. The turrets are really mushy as well. I just picked the scope up, so I think I’m just going to send it back and go in a different direction.
