I know from personal experience, the way my son and I hold and align the rifle to the target, he shoots to the left of my on mine and I shoot to the right of him on his. So yes, confirming it works for the hunter is paramountSeriously… I agree with all the comments about people dropping a rifle with bullets and asking to sight it in .
Then take it hunting next week.
I’ve asked them to come shoot after sighting to confirm their aim point. I most often get the “ if it shoots good for you then I’m good” comment.
A few weeks later they may come back and ask to check zero because they shot five times and missed.
I’ll ask, “how far”.
Then I hear…” not sure, but far” !
We do what we can.
That’s all I’ll say.
