I've not had a high regard for the smarts of a lot of folks, but y'all are giving me a case of the serious shudders!
I'm lucky, I guess. My uncle became an armorer for the National Guard when he was still in high school, and later on became a gunsmith. I got started from the git-go with the whole sight-in deal.
Even though my pet '06 would stay within an inch of the original point of aim from year to year, I always double-checked it before the start of the deer season, and if there had been any severe bump during a jeep ride, I'd check it again.
Did I ever mention I like one-shot DRT?
Hard to figure how a guy could believe in the "X marks the spot" thing. I guess he never, ever, picked up any gunzine and looked at an ad for a scope...
