Full update... while it's easy to point fingers at ATN, I wanted to come on and provide an update on 2 root cause issues. One I put on ATN for poor communication about this best practice, and the 2nd is on me.
1) you need to zero at base magnification first. Shoot a small group, and make the zero. At that point you can use the zoom feature within the zeroing process to fine tune. This is a digital scope, and basically the reticle is being projected onto a screen. If you shoot the groups at anything other than base, it will be off after. This is NOT mentioned anywhere, so I put this ATN.
I did get a chance to speak with one of their directors on a solution... have the zero process be picture in picture. Do a small 10x or whatever window in the top right that is zooming in, while keeping the actual zero screen at base magnification
2) I have my Leshiy at the Dr (tuning oopsie) so I through the 4K on top of the EDgun Veles... shooting off a bench and bipod... the thing is dead nuts accurate. Anyways, there is a bolt on the end of the gun that acts as an adaptor for the LDC. I had taken that off to have John Hagan create an adaptor so I could use my other LDC's from DonnyFL to test. All EDgun barrels use signifiant pressure to hold the barrel in place. I didn't tighten it to spec! I normally have a vortex red dot on the top, which weighs nothing, and more importantly requires no tweaking of the focus, etc. The weight of the 4K scope exposed the issue of the bolt pressure... primarily when I was changing distances and moving the focus. I took the thing apart, threw it in a vice, tightened it down, and boom... pellet on pellet!
I jumped the gun a bit on this one, but as usual... process of elimination eventually got me to the root of the issue, and a solution.
