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

[ntobroken]

Glad your 15-22 tolerates the Remington GBs. Most of the problems I have with the Remington GBs is failure to go bang regardless of how many times the cartridge is struck by the firing pin. I do think there is some variation in different lots of the Remington. Some guns just refuse to feed or fire the GBs.

Howdy Beck, I shoot a lot of 22LR in my pistol and know what you are talking about. I get dud rounds once in a while with the Remington, but I also get duds with the Federal bulk. I've not had any other issues than that from either and it's not that big of a big deal to me. I'll keep buying the economical stuff for plinking around but for hunting of course I'll pick up the pricier and more dependable rounds. Nice rifle though, I'm pleased.

My first outing with my M&P 15-22 I started off with 100 rounds of CCI MiniMags which seem to be the gold standard of 22lr ammunition, Functioning was perfect. Next up was Federal 710s which was also flawless and the most accurate in my rifle. Then tried some Federal 550 bulk pack which was also flawless. So far in 2 range sessions I have yet had a failure of any type, I love this rifle. I even posted a YouTube video mixmatching ammo trying to get it to jam.

I had my first 2 FTF today with CCI mini-mags of all things. Mine loves the Winchester 333 red boxes.

Was that failure to feed or fire?

Feed...I ususally refer to didn't fire as a misfire. I had one of those the other day but it was obviously the round, the firing pin put a nice dent, it was just a dud round. Even with the 2 FTF's today though I'm cool with it, its so cheap and fun to shoot. If you told me the zombies would be at my house somewhere around 4:30 this afternoon I wouldn't be reaching for the 15-22 anyways!!!

Do many of you see the Winchester boxes I'm talking about? I think they are super x's...its a red bulk pack and it says 333 on it. My rifle loves em and they are really clean burning/accurate.

No where near as common as Federals and CCI up here.

I have some but have not tried them in my 15-22 yet. I picked some up a couple of months ago at a WallyWorld. I have not seen them for sale there now for a while. As Mark said, Federal and CCI more common also in my area.

Mine doesn't like Remington Golden Bullet and Viper. It works great with all CCIs and Wolf.

 

[CORPORAL PUNISHMENT]

remingon bulk--terrible remington thunderbolts--terrible federal bulk--almost perfect ( mostly failure to feed ) cci standard velocity---almost perfect ( mostly failure to feed ) My rifle is going back to smith. I can understand a few dud rds but I want this rifle perfect.

Has anyone tried Fiocchi ammo?

I'm beginning to wonder if the bulk boxes of any brand ammo have issues. I just got my 15-22 and started off using the federal bulk box as recommended by S&W. Stove pipes approx 10% of time. Switched to CCI Blazer bulk, same issue. Purchases CCI Mini Mags, in a box that protected each round a little better. No issues. To rule out a faulty mag. Tried all three in a friends 10-22. Stovepipes approx 1 - 5% of the time. Mini Mags - No issues. I know that Mini Mags have a little more power to cycle the bolt but this seems like more than just a coincidence. Needless to say, switching to the mini mags. If it starts to have issues again, I'm sending it into Smith for the Miracle Adjustments referenced here.

I have had my gun a little over 2 weeks now and found that CCI Blazer and Federal work great with less than 5% failure. Have not tried the Federal bulk pack yet. Tried Remington and had over 50% failure. Checked the manual that came with mine and discovered they tell you not to use Remington.

 

[lurch_fon]

i just bought mine on the 25th, took it to the range yesterday for the first time. Tried out some Winchester X, Blazer, and CCI.
I had no issues with the cheap stuff, but out of a 50 pack, I had 2 fail to feeds with the CCI. The rounds stood straight up and took a beating. Looking to pick up a federal bulk tomorrow. I went through 250 of the Blazers with no issues. It seems to be a very consistant round.
I had heard a lot of people say the manual states to not use remington. I was kind of eager to see it mentioned, but my manual does not state it, but I will definitely be avoiding it.

I just got 2 boxes of the Winchester 333 and my rifle hates them. 9 misfires in one mag. one exploded out the port. they also caused my m&p 15 to "double tap". it runs flawless with cci stingers, mini mags, Federal 550 pack. Winchester HPs were good too, only very dirty.

Well over 1000 flawless rounds of Winchester "333" down the bore. Only recent failures to feed are all CCI.

Don't buy a lot of ammo until you find what your rifle "likes."

My rifle had the same problem with the CCI's

I second that, dont put anything Remington in your gun.

My experience has been just the opposite!

Of course, nothing is as bad as the Remington Gold but the Winchester 555 did not perform (in my rifle) anywhere near 100%. I could actually hear the difference in some rounds of the 555- a couple to the point of breaking the rifle down to check the barrel for a stuck bullet.

So far, the Federal bulk has been very good. The CCI MiniMag has performed nearly flawlessly. I'm a little over 3,000 rounds now and my rifle has adopted my wife's philosophy--expensive is always better.

Chuck is right-find out what your rifle likes. If you've already bought a couple cases of MiniMags and your rifle doesn't like them, I'll make a cheap offer to help you out.
