No I understand, I was playing devils advocate kinda. I've shot a lot of night matches with just irons and a rail mounted light. And a lot more long range matches in failing light. I understand the virtues of a scope but saying one is required?? Generally I see people buying 6-28X power scopes and are surprised when something is so close as 200 yards and they have trouble tracking the target or can't find it. I guess from what I took from your comment was that you had to scope and dope all the rifles. I've known my share of "old guys" who have trouble seeing the front sight at camp perry. They usually flank me on the line and tell me how lucky I am to be young and not need glasses.
True that. I am not that advanced in my rifle craft. I was happy to be able to hit the 9x and 10x consistently on a B-27 from the 50 yard prone in outdoor slight breeze conditions on a shared Mini-14.
