WMR Reliability



Log in to see fewer ads
Is there any information to suggest that WMR is less likely to have a failure to fire than 22LR?

I am not talking about any other aspect of the two cartridges, just reliability of ignition.

Purely empirical, but I have never (yet) had a failure using 22WMR. In a Single Six or a S&W 48.

I've shot the same old EAA Bounty Hunter for a lot of years and have never had a misfire.

I used to shoot a lot of WMR, quit the round for many years, and have now taken it back up. I can not remember ever having a misfire in the early years and have not had one in my recent revival of shooting this round.

It was my sense that WMR is more reliable but I have never seen anything written about that. With all the rimfire articles written you would think it had been studied and written about. I don't know any reason why it would be more reliable but it seems like it is to me.

It's rimfire.
Susceptible to the same problems as 22lr, 17hm2, 17hmr.
Problems with assembly/components at the factory, rough handling during shipping
and with the rifles/pistols due to mechanical issues or failure to clean build up in the receiver.
Case ruptures, weak cartridges and failure to fire can happen, not if, but when.

You and I must be doing something wrong.
I've had misfires with my WMR's, probably in the range of one out of every couple hundred rounds...worse in sub-zero weather (which I attribute more to firing pin lubrication).
My guns also don't shoot MOA 'all day long'.
Where are we going wrong

Wrong? Nothing wrong, just what we've experienced snaggle.
The larger the reference sample, the likelier it is to run into unsatisfactory results.
A single 5 shot group is not "all day long", especially if it didn't hit where ya' were aiming, eh?

Yep, some of us never have a problem.
Others have to put up with less than desirable results.
Then we end up dealing with customer service.
Been there, done that, got the refund check, twice.

I had some problems with an RAR and sent it back. It was the gun not the ammo. Light strikes and extraction issues. Replaced the bolt. I don't recall ever having a dud that was not the gun. The rounds always fired in my single shot or revolver which had a heavy strike.
If you are having problems in cold weather check your firing pin. You may be getting light strikes.

It separates 22WMR from standard 22 or 22LR. Never remember an ammunition related failure with 22WMR. Have experienced a rifle that would pierce the rim of some with the firing pin.

Seems there is no truly 'bulk' or less expensive 22WMR ammunition either. Perhaps it is true, quality costs and we pay.

This makes a ton of sense to me.

Good quality Firearm..Good quality ammo. No problems. Same with my .22 LR rimfires. I do not use junk ammo, nor do I buy junk Firearms.

In 2019 I had serious reliability issues with a new-bought box on Winchester white-box .22WMR (NOT Dyna-point*, no specific type name at all, no large X on the box, just the Winchester name) - purchased new at Sportsmen's Warehouse.

I noticed that in my Savage A22M it was quieter, and had less recoil - so much less that it never fully extracted.

I then fired it in my OM-SS, and had the same quiet "pop" and low recoil. I checked the barrels on both and were clear of any bullet - but both had yellow crystals in them!

I fired some of the CCI I had, and they worked fine and cleared the barrel of the crystals. I tried a few more of the Win in the SS and the same thing happened, s I threw the rest of the box away (pulled the bullets, then dumped the lot in the garbage).

Fortunately it was a 50-round box, and I had only purchased the one, so it wasn't a bad lesson.


* I already had some Dyna-point, and it worked correctly.
