Sighting in your .22lr

I thought it was worth pulling this together into one post, maybe even making it a sticky.

This has been unashamedly pinched from the Gunsmoke website (link further down).


One of the better methods for sighting in a .22lr is the point blank method.

I'll give a summary if you just want to get out and shoot, and a link to the web page with all the details if you are stuck at a desk at work, or want to do some tricky stuff.

Point blank range is the distances between which a bullet will hit inside a defined vital zone when aimed smack in the middle of that zone. This method of sighting in aims to maximise that range.

For small game, a 25mm (1 inch) radius zone (that's a circle 50mm or 2 inches across) makes most sense as it caters for head and chest shots on most common small beasties we shoot her in NZ.

So, for subsonic .22lr ammo (40 gr), if you sight in at 47.5m (52 yards) you will hit inside the vital zone between ranges of 16.5m (18 yards) and 54m (59 yards).

For supersonic .22lr ammo (40 gr) if you sight in at 54m (59 yards) you will hit inside the vital zone between ranges of 18m (20 yards) and 60m (66 yards).

For hyper velocity .22lt ammo (CCI Stingers in this case) if you sight in at 78.5m (86 yards) you will hit inside the vital zone between ranges of 6.5m (7 yards) and 89m (98 yards).

Beyond those ranges, you need drop charts, or a bunch of practice (guess which one is most fun?)  Grin

If you put 40 gr supers in a rifle that is sighted in point blank for 40 gr subs as above, then the supers will be point blank between 5.5m (6 yards) and 62 m (68 yards)

That means you don't get much extra distance with the required accuracy, just a round going faster and making more noise!  Huh

For all the details, and the drop charts, have a look here.

If you want to have a play yourself, try these links:

This is a simple, metric, web based ballistics program

And this is the imperial version

These don't have drop charts but give you the basic results in a table.

You can lift the basic starting data from the page on point blank sighting in, or you can use this info on basic ballistic coefficients for .22lr rounds.

Hope that is some help to people and have fun out there.  Smiley

Great post and I'm going to try it out.

But you might like to revisit the above were 47.5m (52 yards) = 54m (52 yards). Wink

Hmmm, yeah I messed that one up. That'll teach me for trying to work with 3 websites at once!  Embarrassed

I would fix it, but for some reason I can't edit that post any more.

Perhaps a friendly Duck Gunner will make the followings edits for me?  Wink

Good post Vanman,

I must admit I only shoot subs in my .22lr which is zeroed at 50m.
I did try HV but not really gaining anything, its much louder than suppressed subs and you don't really gain much in accurate range.
If I want to shoot at over 80m+, I used the 17hmr, it's designed for long range,.22lr is not.

Dave.

Very helpful.

If you want to calculate different PoI's for different ammo - say sub's out of a rifle zero'd for HV's here's how...

Use the above links to calculate your regular ammo trajectory. Make note of the Total Drop value at each range increment. In my case my primary is Hypers.

Then load in your 'other' ammo. In my case ... sub's

To calculate the sub trajectory take the total drop differences between Hyper and Sub, and apply that to the Hyper trajectory.

For example, my hypers are zero'd @ ~ 87 yards. At 50 yards my hypers trajectory is 1.23 inches above zero. The total drop value is 1.81 inchest.

The total drop value for subs @ 50 yards is 3.94 inches.

The total drop difference is 1.81-3.94 = -2.13 inches.

Add -2.13 inches to my HV trajectory (1.23 inches)... ie -2.13+1.23 = -0.9 inch.

So at 50 yards my hypers are 1.23 inches high, sub's are .9 inches low.

You can even throw it into an excel chart:

my 22 is sighted for 80m and requires only slight adjustment by me when i shoot depending on range. its good to 100m and anything in between. i just need to account for it. 80 m is a good distance. we shoot hares the size of small dogs and the subsonic nearly bounces off.

Cheers, Just bought a Norinco jw15a will try this out over the weekend. Also hello to everyone, I have been a guest on this site for awhile and just recently registered. Some very interesting topics out there.

thanks for the info. I have my 22lr sighted in so its smack on at 75m with high velocity ammo and haveing it sighted in at that range works well for me Smiley

shoot it in at 15 good paces puts you bang on again at 75 and good out to a 100. We used this method for many years on the rabbit board.

Shooting it in at 15 paces (yards) means you should be able to hit a ammo packet at 100 (aim for the top edge)

All our shooting was done with a ruger and Nikko 4x32  Smiley

i sight in smack on at 25 yards and have no probs i shoot a 22 for a living a lot of the time so im not into wasting ammo as it costs to much

every gun is different and the same with the ammo its what you are used to that makes the difference
  

if there lead in the air there's hope

Just for interest how little energy a 22lr subsonic has

Hi all, what distance would you recommend sighting in a Norinco .22 Magnum?

I've just picked up a 22mag as well, a bit of reading up suggested zero at 109yds for MBPR out to about 130, beyond that you start thinking about drop. 5.8" drop at 150yds I think.

Up in the states .22lr is making a comeback as a short range 60-140meters varmit gun, cheap ammo also . They have an interesting twist on the sighting in story. Unlike most of us here in NZ who mainly sight in at 50/75meters, they sight in for a dead on zero at 120meters.
Then they shoot in at 25,50,75 etc. They note the hold under at these ranges. Their theory is, like pistol shooters, holding under keeps the target in clear view at all times and the long shot-100+ is a straight hold on dead centre. Ive tried this out on the range using metal silhouettes at ranges out to 140 and it really works. shot some bunnies a few days back using this system and shots at 100-120 were easy as I could see the target not just the top os his head at the bottom of the scope

The only issue with that is not a lot of scopes have holdover marks above the crosshairs for holding under do they?

A dialable scope and rangefinder are really essential once you get past 120yds, such is the steepness of the trajectory.

Here's my long range sniper rimfire  Wink



Rifle is a 50's vintage Walther smallbore rifle still capable of possibles on a smallbore range. It now wears a 10x40 3200 scope and taped to the butt is the trajectory in 20yd intervals out to 180yds. I've nailed plenty of rabbits first shot at 130-140yds using SK Match ammo.

nice rig there.  How do you find the match ammo on game?  I've thought about trying out some match ammo to see what accuracy my .22 is capable of, but its a hunting rifle and I've always suspected that the match stuff will be marginal on game compared to subsonic hunting ammo with a good sized hollow point

All I can say is it's easily killed rabbits and maggies at those distances. Once you get down to those velocities, even hollow points can't be expected to expand usefully. Accuracy outweighs projectile design by miles. I have shot some groups at 120yds in good conditions that weren't much over an inch.

sounds complicated to me, my old 10/22 carbine with standard velocity cci target lead rounds and a basic tasco scope and a gunworks can on the front hits everything i shoot at. so i geuss practice counts i dunno the numbers but its a bit low at 50 and dead on at 75 so out to 100 i just aim for the middle of the vitals straight. groups well too. 10 shots just sitting without a rest on the grass all fall under 1" at 50m
