It is what it is. - Mueller Optics 4.5-14x40mm AO APV Rifle Scope

I was kind of pleased with the scope after my initial purchase. It looked great and shot fairly well. I put it on a .17 WSM Bmag. I upgraded the rifle with a new stock, trigger, scope mount etc. At the start up it shot 1.5 MOA. Not what I wanted but reasonable. It did ok on prairie dogs, but for the life of me it was inconsistent.

I purchased this scope last summer and fast forward to January in Utah. I took it to the range to check zero and was surprised to get a 2 inch group... I just cleaned the gun and was not expecting that. After 3 or 4 more groups I started getting some really wild flyers. I bagged the gun for the day. I went to the indoor range to try to figure out the problem. First I put the gun on a lead sledgehammer. I got 7 rounds in a .20 inch group at 50 yards, all shots were touching.

Weird right? So LOOKING through the scope while in a lead sled again I noticed the crosshair shifting with each shot. Never going to fear out of zero, but enough to explain all those flyers. I tried shooting from the bench again, offhand, with the same results. The group opened up to .5 or so with an odd flyer.

I repeated the process enough to determine the scope was not holding zero. I determined it was more due to the cold weather then anything else. As when the gun was warm it was less "shifty" and as it got colder it was more "shifty".

I won't waste my time sending the scope back. It was less then 6 months old. I am not going to go through customer care at Mueller. I took the scope off, drove into the boondocks and at the first appropriate place, threw it into the air and applied a dose of scatter gun.
