I use it for field target, max 55 yards and last weekend was marking out of my side wheel, but consintent though.Yesterday I was comparing with another scope and confirm the diferences even being the second scope also an UTG.Pretty frustrated right now., and no, I donīt touch the magnification at all, is allways at 16x.
Thank you guys for yor answers.I didnīt change the eyepiece either, I guess I will re-range everything again in a wormer day to be sure.Best
