A door gunner giving advice on sighting in a scope? Now that’s hoot, lol, :) Actually, I’ll give you due, your’s is one of the best postings on this thread. I would only add one little item. When mounting a scope, assuming the shoulder stock is the correct length, be “sure” that you have the rear lens about two inches away from your sighting eye. Keep in mind that when shooting at game, one tends to pull the rifle in tighter than when shooting on a range. Aw heck, they’ll figure it out after they get bit a couple of times. No pain no gain :)
That said, my eyes can no longer do that sort of thing, so I have entered the world of optics.
Yeah, tracers are cheating too, but mastering hitting something while there is a lot of relative motion is not child's play....... ;-)
