Derya TM22 help please

My warranty come back fairly quickly. What happened was my bolt and extractor was actually deformed from the charge handle screw.

The deformation caused the extractor to “hang up” and not properly grip/extract the shell. Since its return, been shooting flawless over 1000 rds.
 
I removed the left extractor (punch pin from below bolt) and went to the range today to test. 100% success rate on a bulk box of Federal Automatch. I was previously running at ~8% failure rate on this and more expensive ammo.

Reliable and fun, plus I have a spare extractor and pin. Thank you again.
Thanks for the update. I've not mine to the range much, but was having some similar issues which I decided must be ammo specific but haven't had a chance to try others since. Ill keep this fix in mind. And thanks to the guy who gave us the solution.
 
Can anyone confirm if this problem is fixed after removing extractor?
I sent mine for repair and it still got the same problem.
Since removing the left extractor I went ~1,200 rounds without a single issue.

But that winning streak ended today. I was at ~750 rounds since last clean and lube and I knew I was pushing my luck for a semi 22LR. I am optimistic it will return to 100% reliable once I properly clean the firearm. If not I will update this message.

The TM22 magazines are trash. The followers get destroyed by the bolt slamming into it. Hard to know what other side effects this causes.
 
Had the same problem, tried the same fixes. Decided that 2 extractors is one too many. Removed the one on the left side. No more problems. Plus now it's more aerodynamic and I have free spare parts:).
Weird issue though, no signs of wear or peening, no carbon ring, just empty cases getting munched by the bolt, while it desperately tried to chamber the next round.
Edit: Working hypothesis is uneven spring wear causing uneven extraction. Ran flawless through a Speed Steel match.
Hold on, you can put the left side extractor on the right side in case it breaks? Sorry I don’t own the gun but just wanna know
 
I don’t believe that you can, he probably just meant spare parts for the sake of spare parts, I know I have a little bin of useless “for now” bits n pieces.
As to the mod I tried it this weekend (removing the left extractor) and am very happy with the results and will bring it along all the time now instead of it sitting at home waiting to munch on and ruin 1/2 my ammo lol. Good thing it worked because I was too slow getting my thumb over the spring when i was removing it and you can guess where that spring went….It’s as good as my guess hahahah!
Thanks for the easy solve!
