Sight Windage Graduation

I think that works out darn close Jack. My reason for asking was that I was zeroing a re-barreled carbine this morning. I set a target at about 30 yards to get-on-paper and could not even get on paper. I moved the target into 20-yards and barely got on far left. I had left the windage setting where it had been prior to the barrel change. I had to crank-in several clicks right to get it on the bullseye at 20-yards. I actually wound up with the sight ramp sitting dead center of the sight rails, right where we like it.

Backing up to 20-yards would turn your 3.49” per click to something like .75” (1/5th.). 5 or 6 clicks is about as far as I had to move it to get the bullseye, which equates close to your 3.49” at 100-yards.

I’m old with a muddled mind, but I think my math is sorta right.

Not sure it will be of any use as it is in metric but one of my French Army manual from 1964 says:

3 graduations both sides of central line,

1 click = 1/4 of a graduation = 0.3  µ (micron) = move middle center point of 3.5 cm at 100 meter.

As I went reading the part about the M1 Garand it seems that the clicks and values are the same: they give 1/4 tour = 1 click = 1/4 of a graduation = 0.3  µ (micron) = move middle center point of 7 cm at 200 meter.

Hope this help.

I know at 30-yards I was not on paper, anywhere. When I moved back to 20-yards, I was left on paper. I had to move windage 6-clicks right to find the center of the bull. 1-click at 100 yards would equate to 1/5 of that at 20-yards or .2 inches per click. I moved the POI about +-1.5-inches right with those 6-clicks. So.....after going round-n-round, looks like the 1-inch at 100 yards seems correct.

You know what.....I declare everybody right, because I got the carbine zero’d! 😁

I think I have something else to keep us entertained to post shortly.

Thanks guys!
