Feed problems M&P 22

[drmweaver2]

Just got back from the range where I ran into repeated feed/ejection problems with my M&P 22LR (not the compact model).

Out of about 200 rounds, I must have had a dozen feed problems. The slide either didn't feed at all or only partially fed a round into the chamber. In half of those cases, the round "stood up" out of the ejection hole.

In other cases, the round simply didn't enter the chamber.

And then there were about a half dozen failure-to-eject issues, most of which resulted in double-feeds/double-feed failures.

This is a nearly-new M&P 22, only had it a week and a half and has only had about 200 rounds put through it prior to today. All 5 of my magazines are brand new S&W originals.

Thoughts?

All the same ammo?

Yep. All Remington Golden Bullet Value Pack, Brass-plated Hollow Points. Purchased because it was inexpensive (~$.05/round) and I thought Remington was a name-brand.

Try something else. I've had brands of ammo that for some reason don't work well in some guns. Not that there is something wrong with what you have, it just might not be compatible with that gun.

My M&P FS 22 can be picky. Just because it is good ammo your gun might not like it. I would hope you field stripped and cleaned and oiled if according to the manual. I shoot weekly with a bunch of old guys and we compete against each other will 22LR pistols. It doesn't mater the make or model they all have ammo they don't like. I shoot the M&P FS 22, Ruger III Competition, and the S&W Victory, and a Beretta U22 and they all have something they don't like to eat.

This is a "real thing"? Seriously...???

Hmm. Never considered the pistol might be "picky". I'm a new guy and would never have thought that a commercially produced weapon wouldn't shoot all commercially available ammo in its caliber.

Do a search on this forum and you will see many discussions on different guns that just don't work well with certain ammo. What doesn't work in one may well be the best in another.

You believe that and you are dreaming. That is why when we get new SD guns we run a lot of ammo through them to make real sure they like what we are feeding them.

Anyone know anything about an MP22 CA. Recently purchased one and at the range today had an issue with the slide jumping off the frame on recoil. Ammo was CCI 22 mini mag 40Gr. Switched to 37 Gr still intermittent issue. Any thoughts?

I had to learn this about .22's when i started several years ago as well. Found it was best to buy and try a couple boxes of various brands/styles to see what each pistol worked best with. Now i only buy what works well and leave what does not.
My knowledge is still pretty basic but i believe part of the trouble many can have with 22lr is due to how rimfire works vs centerfire (ie 9mm, 40, etc). Next time you take your 22 to the range take a look at the fired casings and see the markings where they were hit. You probably will see some variation and mix that with how those rounds could be loaded and you can get an idea on why some issues could pop up.
Now for me on my S&W 9's, i am heading to 3000 total rounds fired thru 3 different MP models with zero ammo issues. So i have only seen potential ammo issues on 22's.
Good luck!

Ummm, kinda slow here...Can you amplify what you mean here?

Sorry as i know it can be explained better by others. On a .22 casing thats been fired you may see the mark of impact off to the side, on the edge, etc and not in a uniform and exact location. So if the rounds are not loaded or built at the factory to exact uniform specs some may not fire the first time. Or if the ammo is dirty it could stick instead of ejecting cleanly. Failure to fire and failure to eject are the main issues.
On higher caliber rounds that are 'centerfire' like 9mm you can see that firing impact in the center each time. I assume those rounds are in general built to better specs than average plinking .22 rounds.
Again apologies as i have an idea on what to say but likely dont put it on paper correctly lol.
Long story short is .22 can and will be finicky but can be worked thru

I get the sense of what you are saying now. Didn't think to look at the troublesome round casings. I will next time.

Thanks for the idea.

I have the same model and to date, having fired hundreds of rounds, have never had a failure of any kind, so I am actually quite surprised to find out someone has.

I have shot Blazer, Aguila hypervelocity loads, Aguila SSS 60 gr subsonic, and Winchester plated "RN" which is a very high-grade ammo.

My experience has been that a "reliable" .22LR will chamber anything...since you have multiple magazines, the "problem" would seem to be most likely related to the gun itself and magazine insertion height versus feed ramp and boreline. A mag that is seating just a hair too low is likely to cause rounds to "kick up." A mag that sits too high will likely chamber fine except for interference contact with the over-riding slide which could lead to rounds "jumping" out of the magazine.

If the gun is new send it back to S&W and let them figure it out...not that you cannot do it yourself with a bit of observation, just that you shouldn't have too. A new mag catch might solve the problem.

You are one of the lucky ones. Most people that I know have found a brand or two that just doesn't work well in their gun. I have had several 22lr pistols and they have all had an issue with some ammo. I believe consistency is the culprit. Some companies seem to hold better tolerances in their 22 ammo. I've seen a few through the years that the bullet is crooked in the case for example. For most people it is just an inconvenience since they are not using it for defense.

My M&P22 has had no malfunctions with CCI MiniMags, but when I recently tried some Federal AutoMatch, it gave me about a 10% malfunction rate (failures to feed, failures to eject).

I only have about 500 rounds through the pistol. I will probably try the Federal again after running another 500 rounds to see if the thing loosens up a bit.

 

[pgans67]

I have had some similar problems as well. I try to use the high velocity 22lr ammo and it seems to help. The gun can be pickey but I have never worried to much about it. It's just for plinking anyway. CCI Mini Mags run flawless in my gun but are hard to find in these parts.

Another 5-6 misfires/failure to ejects out of ~170 rounds today.
I've got too many of the same type of Remington rounds left to just throw them out or not shoot them, so I guess I'll just have to grit my teeth and deal with it.

It does throw off my shooting rhythm, that's for sure.

 

[Bayoutalker]

Buy a few of a different kind to see if that is the problem. If it is, shoot these for plinking. If it doesn't fix the problem, call S&W.

Just buy a gun that will shoot them. Sounds like a good excuse to buy another gun to me.

My Buckmark didnt like Remington and can have issues with some Federal. A handful of issues in an hour range time is not out of the question with that ammo. Mini mags and std velocity is near perfect in it though.
My S&W compact 22 has near 600 rounds thru it with zero ammo issues so is what i use to clean out the ammo stock that my Buckmark left behind lol.
I also save ammo that gives me trouble for other family members to try and use up as well.

Seems if there is any consistency among .22lr it's that it can and will vary not only on ammo brand but gun brand for how well it works. And it can take some range time to determine what works best in your setup.
