Only true if there are only 'a few hundred' are on this forum.
Well, in the middle ‘60’s, we shot at 42 inch bullseyes at 1000 yards and hit them. This was with a slightly accurized M-14 and 7.62 ball ammo. Our rifle team was mostly a bunch of draftees and one guy from NYC had never even SEEN a real firearm before the Army. On division match day, he shot the highest score. Army rifle training was, in my opinion, lousy.
I could already shoot when I enlisted.
I am pushing 80 years old. I could make that 137 yard shot with my M1A (Civilian M-14) today from the standing position. Of course, I HAVE kept in practice.
In my somewhat-expert opinion, anybody aware of basic rifle marksmanship skills could make that shot, providing that the rifle was correctly zeroed.
