Could be a different lot of ammo? I had issues with zero shifts on a VX6HD 4-24. I am done with leupy’s now. I own several CA’s and all shoot very well.

I had the vx6hd and several VX5HD’s. Dumped all of them. The rifle wearing the VX6HD now has the 4-32 NX8. Others are sporting 5.5-22 NXSs and Trijicon Tenmiles.Curiosity what did you move to?
The guys at Long Range Only suggested maybe my mag box is bound up. They could be on to something. I did break the gun apart a while back ago to do some deep cleaning, and when I put it back together, maybe didn’t get the magazine Square. Definitely looking at it this evening. It looks like it’s a little tight in there.

OK, now we are getting somewhere.
Did the groups start opening up during a shooting session, or were they fine one time and opened up after the “deep clean”?
Do you clean it after every range session?
How many rounds did you fire before the groups started opening up? In most rifles, after 100-200 rounds, you will see a slight increase in muzzle velocity. The commonly held thought is that this happens as the throat and bore are smoothed out. This could have caused enough of a change in barrel harmonics that the groups started to open up.
Also, if you are cleaning every time, you are changing how the barrel wants to shoot.
Additionally, if you are removing the barreled action from the stock and not putting everything back exactly the way it was, including putting the same torque on the action screws, you are adding variables.
Finally, we’re the atmospheric conditions (temp, wind, etc) exactly the same when you were shooting .4” groups and when you were shooting .9” groups?
