22WMR Accuracy



Log in to see fewer ads
Forgive me folks, I'm feeling a mite cantankerous this evening.

Been reading through the 22wmr forum and seeing what's what.
Awful lot of claims of moa and sub moa out to 100 yards.
Some of y'all have been a touch more realistic with 1.5 to 2 moa plus.
Then there's the "find the brand y'er rifle likes" cliche, which doesn't work, by the way.
So, truthfully, what kind of results does your rifle really produce?
Not for 3 shots...not for 5, not even 10...what happens on target for 50 consecutive shots?
Pick y'er distance, use whatever setup makes you happy...but shoot 50 shots.
Indoors, outdoors, one piece rest, whatever, but shoot 50 at a single target, use a chronograph to record the MV's.
Then take a careful look at that target, and then let's discuss the results.

I know, I'm an annoying old coot, but I prefer facts over exaggeration.

Don't care about 50 shot groups or even 10, no animal I've ever hunted stood still that long.

Aaaah, wkd, should have expected that one....

So you only claim minute of critter, eh?

At least that's realistic.

Do you claim all day long too?

I traded away some nice .22 mag rifles until I realized that I was expecting too much from the round. Now I'm satisfied with the average 1.25-1.5" five shot groups at 100 yards with the rifles I have. Some groups are bigger; some are smaller. One of my favorite rounds regardless.

My four Anschutz 54 in 22LR. shoot between 1/2 to 1 moa at 100 and my 1416 shoots around 1 moa but my quest for accurate 22mag is a totally different story. I have gone through half a dozen of them and currently have four. At 100 yards, the Anschutz 1516 shoots 2.5" to 3.5"; 9422M, 3.5"; Ruger 77/22M, 4"; and my latest, a Magnum Research, cannot do better than 3.5". I'll get my hands on a 1720 one day then I can finally close my book on the 22Mag., I'm NOT optimistic though.

The .22wmr is a hunting round for me too, but I've somehow managed to own some nicely accurate ones too, go figure. I do usually shoot the Vmax bulleted loads.

i gotta ask why you would keep rifles whose claim to fame is accuracy. i have read that a 22mag isn't the top pick for accuracy but 3'' is lousy, especially in a rifle that costs a lot because of its accuracy.
just asking.

Sadly, it's not the rifles that are the problem.
The majority are capable of 1 moa at 25 yards.
It's the ammunition that is to blame for the poor results on target.
Major variations in muzzle velocities, inconsistent brass dimensions,
variations in seating depths of the bullets and canted bullets.
Minimal quality control at the factory for ammo whose true purpose
is close range critter thumping. Raccoon, fox or bobcat at the chicken coop?
Grab the 22 mag and aim for the heart/lungs....job done.
But for punching paper and consistent accuracy, that doesn't happen.

Tis time for all to agree: The .22 WMR is NOT a target round and was not designed as such. It is a kill larger varmints round and it does that very well.

MOST .22 LR cartridges are NOT target quality - which is why there are a few companies that manufacture very accurate .22 LR ammunition. IF you wish to do such things are the PRICE for such ammo!!

IF you, the shooter, can hold still for a 2 MOA shot the .22 WMR will do what it should do.

JMHO

jaia, have you found the .22WMR less accurate than the .17HMR? I know you've done extensive velocity testing with the latter cartridge and have identified the sources of ammo inaccuracy. With the greater expansion ratio of the .22WMR, one might expect slightly better accuracy than with the same case necked down to .177".

South Bender, I have a mARLIN 917VSF in .17 HMR that I can (on a nice calm day) keep 5 rounds in 1/2 at 100 yards. With a .22 WMR? Ain't going to happen. For ground squirrels the .17 is the ticket.. . . . and FUN. THWACK........

My quest for a MOA 22 WMR: I was a centerfire benchrest competitor for several years. I became interested in ultimate accuracy of the 22 LR and that lead to a couple of years of building rifles and benchrest experimentation. I had a Ruger 77 in 22 WMR and threw it into the mix. Tried five makes of ammo and none would shoot better than an occasional 1.75" groups of 5 at 100 yds. I rebarreled the Ruger with a BR quality barrel and that brought the best ammo down to about 1.25". I was not satisfied and went to a better trigger, BR stock and a good scope. Still only an occasional 1" group even in the best of shooting conditions. I had a tight chamber reamer cut and rechambered the BR barrel. That resulted in about half of the groups shot hovering right around 1". Compared to the 1/2" groups my Kimber 84 Government Match benchrester was getting I was not happy.

I put the chronograph to work on the 22 mag ammo. The lack of maker's quality control proved itself immediately. As a final test I rechambered the BR barrel with a match 22 LR reamer. Shot many 3/4" groups but nothing like the same ammo would do in the Kimber. I finally got tired of spinning my wheels and went back to the OEM configuration on the Ruger. It is what it is....a close range varmint getter. Fortunately I have several handguns in 22 WMR so all that acquired mag ammo still has a use.

over a lot of years i have gotten the opinion that the 22wmr just wasn't up to a 22lr or a 17hmr. but i swear in the last couple of months i have read at least one thread with people talking about their wmr's shooting 1moa or less. so what's the story. where are those 1moa shooters that i know i read recently?

Those moa/sub moa results are due to fluctuations in ammo quality.
It can't be all bad. Some of it has to come off the assembly line as designed. Not often.
When you get a box that was actually manufactured to spec, amazing things happen.
I've had it happen myself. The next box went back to being blech.
