Or is it only happening with the larger IPS10 battery? Or are you sighting in with one battery and using another battery for hunting?
For me the battery has nothing to do with it. However, I typically have the same battery in for both sighting in as well as for hunting. I actually have 4 batteries. I have a Trail XQ38 and a Helion XP38. Both came with the standard 8 hr (IPS5). In addition, I purchased an extra IPS5 and IPS10. It doesn't matter which battery I have in. I did have a theory for awhile maybe the voltage was changing with temp changes, so I tried shooting with a warm battery, turned off the scope, replaced with cold battery, and shot again and POI stayed perfect. I can turn the unit off and on 10 times, take the scope off, NUC it as many times as I want and put it back on with my ZRODELTA mounts and it stays perfect. Temp drops 20 degrees, and the POI starts to drop, and no my loads don't do this with a standard scope.
