Unique jam

Bought a used 10/22, no info in previous owner/maintenance. Cleaned and oiled thoroughly and properly. Replaced recoil spring assembly with the Ruger factory part before firing it (old one felt very grainy). Everything else looks good mechanically

Using the Ruger 10rd rotary magazine and decent ammo (CCI mini mag, winchester super X) I'm getting this failure to feed (photo attached). Happens about 5 out of every 250 rounds. Ejects the spent case but gets stuck pushing the new one in...any ideas? Or is this just normal? Can't find this type of jam anywhere online

It looks like the bolt went back far enough to eject the empty shell, but not far enough back to pick up the new round. Could be just your new recoil spring assembly needs to be broken in, or even a underpowered round (it happens with the best of ammo in .22), or even though I know you said you lubed it, could use a squirt or two more. And, it could be the magazine. Anyway, welcome to the forum.

Welcome to the forum. Looks like your using HPs, I have had problems with HPs feeding. The flat nose seems to get hung on the lower edge of the chamber. Not every time but enough where I stopped using them.

Another thing that I do is clean and polish the feed ramp on the mag itself. I had a couple that would leave marks or grooves on the nose of the round when feed across the ramp. I noticed that there was a bit of a burr on the inside. Used a jewellers file and cleaned up the burr and polished the ramp. Made a difference with less feeding issues and improved accuracy some.

Also the way the mag fits into the well can cause issues. If it is a lose fit and drops down a little at the front, (chamber side) this causes the round to scrape across the lower edge of the chamber. Which mares and scratches grooves into the nose of the bullet, decreasing accuracy and causing feed problems.

Good luck I know with a bit of playing around you'll get her working great.

Did it happen more with Winchester ammo or the CCI ammo? About the same?

I don't recall for sure if I had problems with the hollow points in the 10/22s. I have with the MKIII. They catch on the feed ramp. Try round nose and see if that solves the problem.

It's a optical illusion - it's is the front part of the magazine.

Make sure the rifle is tight against your shoulder. You do not want the rifle to absorb any of the recoil. All of the energy of the recoil needs to be transferred to the bolt. A 22lr has a small amount of energy as it is, and it is all needed to work the action cleanly. I will also disagree on adding more lube. It is a 22 caliber rifle. Not a high performance engine. 10/22's seem to run better on almost no oil. Once I am done lubricating mine, I wipe those surfaces off with a microfiber towel.. It wall have enough lube after that to function perfectly and be protected from wear and corrosion. Just my 2 cents.

I agree with your 2 cents

The Winchester super-x aren't the same as they used to be before the ammo shortage. They don't function that well in any of my semi auto's so I just use them in my bolt action, levers, and revolvers.
Try different high velocity ammo.

Thanks all for the awesome responses! To respond to a few comments/questions without quoting everyone;

The jam happens just as frequently regardless of ammo brand

Prior to lubing the exposed bolt face (in hopes that the jams would go down) I had closer to 2 jams per every 300 rounds, so I definitely don't want to oil more as it seems to hurt not help

Good comment on tucking the stock into myself, I am new to rifles (coming from a handgun background) so I'll definitely try that

Will also try more round-nose ammo and a different magazine

Clean, then completely remove lube in chamber and receiver, lube receiver with Dry Lube only. I use Rem DriLube.

It appears as thought the mag spring may not be tight enough to push the next round up quick enough so the bolt is over riding the base of the cartridge.
