Out of curiosity what’s the furthest shot you have ever taken hunting and have ever taken at the range? How many rounds a year are you shooting through a rifle annually?
The ability to shoot eastern deer at short ranges does not require a great level of mechanical accuracy or shooting skill to be a successful hunter. A zero shift of 3 MOA would have zero practical impact under those circumstances. I am not trying to degrade your hunting success but rifle skill and mechanical accuracy is virtually a non factor in the type of hunting you are posting about.
If you go over to the scope evaluation threads you will see a quantitative methodology repeated with dozens of optics. If you read them all you can make your own conclusions but scopes moving in rings is a very common issue as is overall zero loss. Loctite helpsThe number of optic trials is significant and many take place over thousands of rounds, very likely more than 10 years, or quite frankly a lifetime of ammo for many hunting setups.
You may well come to the conclusion that attention to detail is not required for your type of shooting while hunting but it’s ignorant if you think that shooting 40 rounds/year inside of 100 yards produces the same knowledge as shooting thousand or tens of thousands rounds per year at 10x the distance.
