Ruger 10/22 bullet drop question

[Sobieski]

Inexperienced shooter here.

I sighted in my 10/22 awhile (years) ago, and I think it was 100yd, but could have been 50yd.

Took it to the range recently to sight in at 25yd for Appleseed.

First round out was 3" high (red circle).
Took me 4 tries and 16-20 "clicks" of adjustment (1/4MOA per click) to hit center of the X-ring.

For those with more experience, if I had sighted in the rifle at 100yd, aimed at the 'X' at 25yd, would you expect the first round to impact where the red circle is, 3" above point of aim?
Is there a way to know whether my old sight-in was 50yd or 100yd?

First off, are you shooting off a bench rest..?

Normally about an inch high at 25 will put you close at 100, depending on ammo...check out a balistics calculator, federal has a good one for their ammo

22lr ammo is all over the place with velocity

like you say MAYBE depending on ammo but im pretty sure the ammo would have to be high velocity.



these are field verified drops and velocity over a magneto speed...eley edge ammo....

Something's not pencilling out with your adjustments if your scope has 1/4 MOA clicks. 1 MOA at 25 yards should be around 1/4 inch. So 3 inches is approximately 12 MOA, which would be 48 clicks on your scope. Unless your scope has 1/8 MOA clicks, something else besides your scope adjustment is in play; possibly your barrel being seasoned by the bullet lube after not being shot for years, or the barrel heating up, etc.

In my experience with .22 LR, if you are sighted in at 25 yards, with the drop you will also be on at 50 yards. In smallbore competition, where we shoot 50 and 100 yards, with a zero at 50 yards you will be around 7" low at 100 yards.

If you were 3" high at 25 yards, that would be approximately a 12 MOA adjustment, and with 1/4 MOA adjustments, it would take 48 clicks on a scope. With 1/2 MOA adjustments, it would take 24 clicks on a scope.

Assuming identical conditions & ammo, a 3" at 25 corresponds with a 125 yard zero. However it's doubtful the conditions were identical, and as mentioned there's a lot of variability with .22 ammo so a 100 yard zero is plausible.

A 50 yard zero is almost identical to a 25 yard zero so that's not it.

According to Nikons Spot On ballistics program a 40 gr 22lr velocity 1240 fps when zero is at 50yds the bullet will drop 5.64 inches at 100yds without any consideration for wind/temperature/humidity or elevation.

I was shooting off a bench rest, so as accurate as I can. I think the groups sort of bear that out.

Comments about the 48 clicks are jogging my memory. After the first two adjustments, I saw it wasn't moving POI much gave it some extra "sets" of 4-clicks. I don't think I did 48 total, but maybe the rest of the distance was my poor shooting.

Thanks for everyone's replies and help. Next time I take it out, I'm going to shoot the 25yd zero at a 100yd target and see what happens. I'm guessing like 12-14 inches low? Off the paper?!?

Depends on the ammo, but if it were CCI Minimag 40 grain, then just over 6" low.

Your chart is too small, could you re-post with larger picture resolution ?

with a 25yd zero and assuming your right around 1050fps at your muzzle you will be right around 7.5" low at 100yds.
