Purchased a new WK compact and have had 2 poi shifts within a week. First time I noticed yesterday morning when shooting at starlings in my orchard. They were only 37 yards away. By my range card that I made after the first zeroing (My 2nd zero is at 50yds) it should’ve been 1 mil hold under. My poi was actually 1-1 1/2 mil low consistently. So I put up a shoot and C at 50 to check my zero. And sure enough it was hitting low at 50 yds. I thought ok, maybe I accidentally turned the turret when resetting zero. So I re zeroed the gun. 1 jagged hole at 50 yds. I was shooting small rotten apples off the trees at 70 and 80yds. Everything was well. This was yesterday afternoon. Came out this morning to shoot the starlings in the trees and at 37yds again and missed twice. Not even touching the bird. At 37yds the whole center cross hair is on the bird (@10x). So one landed at 50 and I took a shot thinking maybe I’m not holding correctly. Completely missed. My spin target was still up from yesterday so I checked and I’m hitting 4.5 mil low at 50yds!!!! I have no idea what’s going on. I haven’t made any adjustments to the gun or tinkered with anything other than the first cleaning of the barrel. Checked my pressure and I am sitting at 200 bar this morning.
My scope is an Optisan EVX 5-20X50i
Any help would be appreciated. Sorry if this has been addressed somewhere else. I searched and couldn’t find anything on this.
