10/22 Rotary Mag Jamming

[trabn]

Hi all, hopefully this isn't a repeat question but I'm struggling with the search engine on this site...

I have a brand new 10/22 and it's firing well but on my first venture out I noted that I would consistently get a failure to feed on the third round whenever the mag was loaded to it's 10-round capacity. I tried loading it up to a lower amount sequentially and found that on ten shots it jammed consistently, nine shots it jammed a few times but more randomly, eight and fewer I had no failures.

Are the springs in fresh magazines relatively stiff? I am expecting it needs time to work-in, but maybe I am wrong and this is a defect.

I've never had a problem with 10 round 10/22 mags, but that's just my experience. It doesn't mean that it can't happen. Do you have more than one to try? If it's just the one that's causing it, get a few new ones and trash the one that's being a POS. They're not super cheap but not super expensive either. 3 packs can be had for like 75$ or so and then you'll have a few to use.

Take the mag apart, clean it & adjust the rotor spring tension.

What kind of jam? Does the bolt pick up a round and round miss the chamber? Is the round popping out of the mag? Does the bolt just get stuck on the round and the round won’t strip off the mag? If you load up the mag and just cycle by hand can you cause the same jam? Have you tried other types of ammo?

I would agree a good clean and tension adjustment would be good, maybe the new mag has some packing grease or something in it. The only time I’ve had issues with a 10/22 mag was when the last couple rounds wouldn’t present but that was because we were kids and no one cleaned the gun since is was new and it was older than us….

The failed round is typically stripped but doesn't manage to seat in the chambre. The bolt closes and 'pinches' the round (you can see a dent in the soft metal of the bullet head when it is removed).

I haven't thought of cycling the bolt without firing - will give it a try. After that I'll try and put a few hundred more shots through it then take it apart if it continues.

Thanks all for the feedback.

What bullet are you shooting? Remington Yellowjackets used to do that in mine.

This is the answer. i had ftf issues with a new set of clear mags. adjusting the magazine allowed proper feeding

There’s nothing wrong with the mag if the rounds are making it into the chamber. It could be residue in the extractor cut in the barrel or just a dirty gun or ammo the gun doesn’t like. Just my opinion

Highly doubtful, but if you're in the SE Corner of BC, I can lend you 5+ 10/22 mags to test out to rule out variables

What ammo??
I have been having fits lately with Winchester 333 bulk ammo in my 1022 rifles...the only semi 22s I have.

The 333 rds have loosely seated bullets which turn freely in the cases and deform and or allow the bullet to tilt when chambering and jam

Ive given up on this ammo in the 1022 ....and in general for this reason

A wise decision, bulk ammo is usually unreliable crap.

What you describe is a curiosity, for sure - if the issue is with the round in the chamber, not sure that I understand how the magazine is involved with the problem - but what do I know - there is a bolt action Savage 93 17HMR here that will regularly run the bullet tip to hit the rear of the barrel, below the chamber - so I am quite sure that one is a magazine alignment issue - all though it will feed the next mag full just fine - there is total of four magazines here that I can make each do that same thing. My 10-22 is serial number 117-6###X, so was made in 1978, which is about when I bought it new. So one mag must have came with the rifle - three others are Ruger brand "spares", but I no longer know which is which - all seem to work just fine. I have had miss-fires with some ammo in that rifle, but I do not recall it ever bobbling the feeding or extraction/ejection.
