What ammo doesn't work well in the MP 15-22?

[RedNeck Jim]

Any feedback on Winchester M22?? that seems to be showing up quite a bit lately...

Before I started shooting suppressed, I shot a fair amount of this and still use it in my Buck Mark. Granted, my 15-22 doesn't seem to be picky with ammo, but this M-22 did (and does) real well for me. It shoots as clean as CCI for me. The ammo is clean & not all greased up plus the black bullets look cool. I especially love you get it in batches of 1000. This selling 100 or 50 at a time is a joke.

Been pleased with most ammo

My 15-22 has had no real issues with any ammo I've been able to track down since I picked it up in April.

CCI Standard, Sub, and Mini-mag have all run flawlessly.

I've shot Remington GB and Thunderbolts with only a few FtF and the GB not holding the bolt open on the last round.

Winchester 333 have been surprisingly clean good rounds.

I think QC may have gotten better as less and less newer 15-22's seem to have any real issues firing most bulk ammo.

When I find out I'll let you know! Technically CCI Quiet rounds don't cycle but that's kinda expected.

I have just over 9,600 rounds with my 15-22, using all kinds of different ammunition. My failure rate is .28%, with most of those being failures to fire. Those I can attribute to the rounds and not the rifle. So far, mine eats anything and everything!

I stay away from anything under 1200fps. Have 550 rounds through mine (500 CCI Mini-Mag and 50 Remington Vipers) with zero issues.

I have tried three different subsonic rounds with the 15-22, all without any failures...

Aguila SSS 60g LRN @ 950 fps
Remington\Eley Target Rifle 40g LRN @ 1050 fps
Remington Target 40g LRN@ 1150 fps

I have a few different types I hope to try out soon. Of course, these are my results, and others may not have the same success.

Do you realize your most accurate 22lr ammo is usually subsonic? Check out the expensive match ammo. Do you realize that most of us that shoot suppressed use subsonic ammo? I almost exclusively shoot subsonic ammo, normally CCI Standard Velocity at 1070fps, and my 15-22 could care less.

I understand the use of subsonic but I do not shoot suppressed. I'm not doing any competitions with my rifle, simply enjoying it. From reading what's around here i understood the consensus was anything 1200fps should work with no problems. That's what I want, no problems.

Yes, the consensus is anything above 1200fps works, but that does not mean that anything under that speed causes issues. Likewise the consensus is subsonic ammo works great too... especially those above 1000fps.

My point is only to clarify. Your post implies that subsonic ammo might cause issues in the 15-22. It simply does not. It is used by many shooters... some almost exclusively. You have put 500 or so rounds thru yours. I shoot that much subsonic every week, and have no more issues with it as with the high velocity stuff. Actually, I seem to have more issues with hollow point mini-mags than anything. It goes at 1260 fps, so go figure.

I think a better way to word it is the consensus is any good ammo above 1000 fps will work without issues in the 15-22. Every gun is different & a very few appear to have more issues than most, but from my experience & from what I've read here, few should have issues with anything running above 1000fps.

Yep, that is some good ammo. I have a few thousand rounds of it and guard it closely. As I'm sure you know, it is the cream of the crop of the CCI Standard Velocity production run. The best becomes Green Label & the balance normal Standard Velocity.

We Don't have a rimfire ammo shortage here in the UK fortunately and the green label is plentiful here as most people consider it too expensive but it is such good fodder for serious target shooting! All the more for me!

I have shot CCI Mini Mags and Winchester without issues. I have not tried anything rated sub 1200fps.
I have some Aguila Interceptors, but have not tried them yet. They are MV 1475fps and a 40 gr Bullet. I shot them out of a Ruger MarkII and broke the hinge on the bolt stop post. So, I have been a little reluctant to feed them to my M&P-15 .22LR. Concerned about battering and spring strength and durability. Anyone have any experience with these in their M&P-15 .22LR?
I read a post here about a test firing for accuracy, which demonstrated good accuracy, but made no comment on wear and tear to the rifle.

I haven't tried any 45-70 yet, but I'm pretty sure that it wouldn't work very well and would probably kill the shooter.
On a serious note, the only ammo I had problems with was some CCI Mini Mags. I had shot them before with no issues, but I had a batch that wouldn't feed properly and seemed to have an excess of wax coating (or whatever the coating is) on the rounds which might have caused the issue. In the end I mostly shoot the Federal Bulk Packs you find at WalMart which work well.
