Federal Bulk and/or 510B's Run fine in mine also had good results with Winchester 333,Remington Ammo = Problems,I believe there is a list of Preffered Ammo in the 15-22 Owners Manual

If all these ammo makers were really into customer service, and putting out a quality product then they should send everybody on this forum 10,000 rounds to try and we can send back our evaluations...sounds good to me. Come on ammo makers who's first?

CCI Makes A New 40 Grain Plated AR Tactical .22 For These Rifiles. Round Nose 1200 Fps 375 Rounds Per box Approx $25.00 Per Box

Federal game shok, is the most consistant and reliable, that I have used. Never had any malfunctions with this ammo. On the downside, it is quite hard to find in the 100 round boxes.

Any body using the CCI Velociters with any succeess ? Saw on Cheaper Than Dirt the MP 15-22 didn't like the Velociters.

Interesting.

I see poeple say brand x works and brand y doesn't. Others say brand y works and brand x doesn't. Seems everyone just needs to try out and find out for themselves.

For me, Federal Bulk 550, CCI Blazers work great.

Remington Golden bullets, I haven't tried since they were specifically in the not recommended list, yet I've seen some say they work great.

Personally, I've had two boxes of winchester 333, and have feed and firing issues with them in all semi autos. I've used up my last box, won't be buying anymore. Got a ton of older winchester, all of which (including the 333) are stamped Super X on the case, yet the older stuff works fine.
I don't mind the occasional FT fire, but I don't like FT feed at all.

ive been using ccl mini and eley subs never had 1 ftf or problem in over 1000 rounds

I have settled on Winchester Super X. Perhaps one or two FTFs in 2000 rounds. I broke the gun in on CCI Mini Mag and had perhaps 6 FTFs in 500 rounds, all of which fired after a second try.

I tested this round and they group really well, If you observe the recoil on the 15-22, they run a little hot and the rifle absorbs a harsh vibration with each shot as compared to a normal ~1200fps round. The CCI Velocitor runs at 1435fps, which is slower than the Stinger, but I assessed it didn't feel right for the 15-22's plastic frame to take over and over again.

guess im the lucky one. have shot all kinds of ammo besides subsonic thru mine and all fed flawlessly. i am wondering if its a magazine issure instead of a gun issue. went toe to toe with freshly cleaned ruger 1022 the most overrated 22 in my opinion and kicked serious butt with accuracy and feed issues. but then again my marlin model 60 would do the same thing. just wondering if its a mag issue thoughts welcome. maybe if 2 owners got together and traded mags what would happen

I just commented about this in an earlier thread, "Weird ammo question". It seems S&W has found that some work and some don't. I think I narrowed it down to the hollow points and smooth tips. The hollow points stovepiped a tremendous amount of times where the smooth tips didn't. So much for their recommendations

hmmm, the win super x IS recommended? wow we couldnt feed more than 2 or 3 without a jam.

yeah.. that seems to be the name of the game.. try a ton of different ammo and see what works the best

Thank god I'm not the only one, I thought it was just my rifle

Wow, thats an awesome test. Thanks for sharing your results.

Humm. Very interesting on the pounding the CCI velociter handed out. Thanks for your testing and input on this subject.

Do not use Walmart's Winchester 333 bulk box.

I shooted 2 magazines of CCI from walmart NO PROBLEM, I shoot 1 Magazine of Winchester 333 bulk box HORRIBLE, it took the fun out of firing.

(3) Failure to feed
(4) Failure to fire
(2) Jammed (see picture)

After the last jam I decided no more shooting with those 333, I loaded my MP15 with CCI's and problem solved.

I did a bold thing the other day. I bought 1k rounds of this stuff. The first 500 have been fired just easy shooting with absolutely no troubles what so ever.

Last Friday was our equivalent of indoor hillbilly christmas tree choppin'.

As I stood in front of my ammosafe I decided to grab a full box of 500 rounds of Winchester Wildcat and put my 15-22 to the ultimate ammo test. Throwing 500 wildcats downrange - fast.

I had only 1 failure. Ammo related, not the gun - round wouldn't even go off in a .22 Diamondback revolver.

Only thing I can say is that the grouping is a bit wider with this ammo but hey - if ones choppin' down a christmas tree... who cares?

Just finished cleaning and I haven't found any irregularities.
So here's the question: why does S & W not recommend Winchester Wildcat- ammo?

cdesigns: "Do not use Walmart's Winchester 333 bulk box."

I'm not a real fan of the Win 333 box in general, but they shoot fine in my 15-22.

I have a hard time getting any .45 auto ammo to shoot. Doesn't matter what brand I use.

Out of your 15-22?

I can see how that would be a problem.

All rifles are different and so are the different batches of ammo. Mine hates the CCI Blazers, at least the brick I have now.

I doubt I`ll buy another batch of blazers , but if I did , they might behave better, but I`m unwilling to find out , after the poor results i`v had so far.

I like many others have not had good luck with Remington Rimfire Ammo,But have had good luck with Federal Bulk & CCI.

So no magazine, lock the bolt back and just drop one in the chamber while riding the bolt forward slowly? Or do they work well in the magazine and able to slide in with an un-altered feed ramp? I'd like to shoot these for fun

I had the same problem with the Winchester 333 and 555 ammo from Walmart. So far I haven't had any problems from the Federal bulk ammo I just bought. We'll see how it goes when I finish the box.

Hmmmmm. I shoot Remington golden bullets all the time. Out of 550 rounds I had only one fail to fire, bad primer, and that's it.

Not sure if its been mentioned but my manual actually recommends NOT using remmington. LOL

Just got my 15-22 today for Xmas and 4 boxes of remington GB ammo. Sounds like my grandson will have lots of ammo to put through his marlin 22 tube feed. I'll need to find some federal or CCI ammo and give them a try.

i got a cheap box of winchester wildcat .22 ammo (but the shells said super-x on them so did winchester just relabel them?) and have had one FTF out of 400 rounds. i'll call that a fluke.

seems to like the federal bulk pack and so does my wallet!

I just went through a brick of 550 Remington and only had 2 misfires. Maybe I got lucky, but it worked great in my SW M&P 15-22.

Federal,CCI,and Winchesters work excellent. Stay away from Remingtons.

Remingtons run just fine.

I had trouble with the win 333 ammo in the 1522 my son uses. We do not use it. We stick to fed bulk for plinking and squirrel hunting. It works really well so we see no need to change. The winchester ammo made quite an impression on my son. I don't think he would use it if you gave it to him. He couldn't get it to fire with his single shot davy crickett. It caused him to miss a squirrel and he was done with it. He had 4 FTF's-failure to fire, squirrel got away and dad was laughing.

Since this is my first rifle ever i'm still new to the whole ammo deal but have been reading up. Guy locally is selling a brick of Eley Sport Std Velocity. This any good?

Eley is good ammo. Some consider Eley Match to be the best match ammo available.

I've had really bad luck with Winchester ammo in my 15-22. Whether its the white box, super -x, or M-22 they all fowl the barrel with lead very badly. I've used those 3 products and had the same result. They function good and produce decent accuracy, then after 250-500 rounds I notice that they start to key hole. Then it's to late. At first I thought it was just the white box which fouled after roughly 500 rounds. I tried super-x, and had identical results. At this point I had given up on Winchester, until I found 1000 rounds of M-22 on sale at Walmart. I was Leary to buy it, but since it was designed for this style rifle I figured I would give them another shot. After 250 or so rounds there I was beating a wooden dowel down by barrel trying to get out the lead. That last time it took me almost a week to get the barrel clean using several products to remove lead fowling. I don't know if its just my particular rifle or what, but my 15-22 will never see winchester ammo again. It runs fine on all other ammo. I have ran 2500 rounds of blazers through it in a single session without a hint of fowling.

Thanks for the quick response.

What about Federal lightning 40 grain high velocity? Guy had a couple 500rd boxes he's trying to sell.

Virtually ANY standard or high velocity .22 will most likely do just fine in a 15-22, no matter what the brand. There's altogether too much worrying about what might or might work. Just load it up and shoot it!

Like others, I have had good luck with Blazers, mini mags, stingers, and also the Federal Auto-match bulk pack. Have some of that CCI at tactical but haven't tried it yet

Yea with the ammo shortage I've started trying other ammo that I wouldn't ever try before... all I use to shoot was CCI and sometimes Federal... come to find out my rifle will literally shoot anything I put in it...so yea just load it and try it you might be surprised... I was...

The ammo recommendations in the manual are just that. Recommendations.

My personal go to bullet is the Remington Golden Bullet and I consistently get dime sized groups out of my rifles with them at 50 yards. People can talk **** about them all day long and that is cool with me, cause in this time of ammo shortages, I'll take them all.

So far, I have tried

CCI Mini-Mag 40g CPRN
CCI Tactical - 40g CPRN
Federal Champion 36g CPHP
Fiocchi "Canned Heat" 40g CPRN
Remington-Eley Target Rifle 40g LRN
Remington Golden Bullet - 36g CPHP
Winchester M-22 - PLRN

Almost 5,300 rounds with 13 failures.


Still have to try these...
CCI Blazer 40g LRN
CCI Velocitor 40g CPHP
Federal 36g CPHP (325 Value Pack)

Mine seems to shoot about anything I feed it! If I find one that doesn't work well, it will go in the Henry Lever Action.

That is so very true - and they were written several years ago and have never been updated. That's why I tell shooters who ask about them to simply ignore them, as both lists are woefully out of date and do not reflect current ammo production.

Or the current rifle production... early 15-22's had issues the "new'er" ones don't... which is good for everyone...

Finally made it to the range today to try out my new toy. MOE in FDE.

375 rounds of bulk Federal, 200 rounds of CCI standard velocity and even 100 rounds of some Remington Thunderbolt my buddy had.

CCI ran flawless, but seemed less accurate than the Fed.

Federal bulk ran great. 2 FTF with good strike marks. 1 stovepipe with FTE near the end. We both thought the most accurate.

Remington all fed and shot fine. But some loads sounded "weak". Also had a strong smell that we didn't notice on the others.

But I have to say we had more f***ing fun with this toy than I have had in a long time. So glad I pissed the wife off and bought another gun!

My LGS threw in a box of M-22 when I bought my M&P 15-22. Some of the cleanest burning 22lr I've seen. Good groupings as well and no FTEs.

It is copper jacketed so I don't understand your lead fouling issues here. I managed to get 2000 RDS at Wallmart yesterday morning and was elated. First guy in line bought 3 boxes of 555. He can have 'em. He apparently thought the big black boxes of 1000 RDS were some center fire.

I paid $100 for 2000 RDS of what I consider good bulk ammo for the 15-22.

I don't get it either. It's the weirdest thing. Once again (stupid me) I ran across some WIN super x, and low and behold I was spending 2 hours cleaning my barrel to get rid of the fowling. I ran 333 rounds of federal through it at first. Once that was gone, all I had left was the Winchester. I broke down my rifle and inspected the bore and it looked good. I ran my boresnake through it a few times just for good measures. Then ran probably 200 rounds of super x before I started to notice accuracy problems. I broke the rifle down again and inspected the bore and just like every other time there was significant fowling about 4" past the chamber. I caught it early this time so it wasn't quite as bad to clean. Once I got home I cleaned it. When I was done I had a pile of lead shavings that was bout the size of a nickel. It must just be my rifle, but every time I use any Winchester ammo this happens. I'm a clean freak, so my rifle never starts the day dirty, it just hates Winchester ammo. I can and have run 2500 rounds of CCI blazers through it in a single session with zero trace of fowling. It kind of sucks that it does that with Winchester ammo. It runs it good, and accuracy is good, it just leaves lead deposits/shavings in the barrel, even the M-22. Luckily this is the only ammo my rifle doesn't like, so there are quite a few options left. It even runs Remington golden bullets like a champ. It's just a weird deal.

Ok...bringing back an older post by using the search function. Today at the range I was running some Federal American Eagle's thru my 15-22. I stopped after 100 or so rounds because I was getting to PO'd. This is the first time I have used this ammo and I had nothing but issues. Out of a 25 rd magazine, I would have 7 or 8 FTE's. Then reload and have another 7 or 8 FTE's and so on and so on. I have run CCI's thru with no problems. Anyone else have this issue with the American Eagle's? I am going to clean it again tonight and go back tomorrow with some Federal bulk, CCI Tactical's and some Blazers and see what happens.

Since we are reviving an old thread;

Bought some Remington Thunderbolt thinking it may have been improved since I last bought during the late 80's, (only thing I could get my hands on at decent price) Nope, still a PITA. All rounds cycled just fine, but I noticed that after 50 round the groups started to open up. Looked down the barrel and notice it was severely leaded up. So I just blasted away the other 450 and will consider it a lesson re-learned. All 500 round cycled perfectly though, shame really......
