Last time I'll ask about MOA

New Ruger 10 22 I have a Simmons scope mounted on it. The MOA is 1/4. Now the fuzzy part 4 clicks = 1 inch at 100 yrs well how do I figure it out for 50 yrds

The quickest, easiest way to sight a scope on a rifle, no calculations needed, is to first shoot a shot, then secure the rifle in the rest as best you can with the crosshairs on the target. Then use the adjustments on the scope to move the crosshairs to align with the hole you just shot. Even if you can't get the rifle perfectly motionless on the bag, it will get you closer, quicker than trying to click your way there.

If your scope doesn't have enough magnification to see the bullet holes at 50, just start at 15 or 25 yards with this technique to get your scope sighted in and then move out to 50. Usually, with a scoped 22 rifle sighted in at 16 yards (50 feet) with HV ammo, you'll be very close at 50 yards.

Using this approach, I've never needed more than 10 shots to get roughly sighted in at 50 and, typically, only takes half of that. I then spend the rest of the session fine tuning as needed.

I knew you could do that with the old Russian PU scope for the 91/30 but thought modern scopes were different. With the PU scope only the crosshairs (or post) move but not the entire sight picture. The PU sniper rifles you see today all have modern made mounts which are of questionable specs and often you have to adjust the post where you can clearly see its not centered in the scope. The scope has enough adjustments in it that is possible to have it almost to the edge.

So I take it this also works on a scope where the entire sight picture moves?

1 click = 1/8" at 50 yards.

I'm going to try this way sound's to be easier than counting clicks. The gun club has had 5 feet of snow for a few months. They plowed it all off the ranges yesterday. I'll see how this goes. Thank you

That's the way I always do it, the last year anyway, since I read about it. Works great.

The hardest part is not moving the gun while you're messing with the adjustments. That's were a rest that allows you to lock in the gun comes in, handy.

I've always just fired 2 rds at 25 yds. If they are grouped closely together, I move the knobs, counting the clicks. check again with 2 rds, move again if necessary to get things right where they oughta be, then back off to whatever the zero range is going to be and fine tune. Normally, 4 more shots at that distance is all that's needed, barring a stray gust of wind or a brain-fart.
