TM22 Issues

[u/AHangryBeaver]

So, I will say it’s gotten “better” after putting about 350 rounds but my current issues are:

Not so much failure to eject but failure to chamber a round/cycle a round. - I’ve found loading 8/9 rounds per magazine instead of 10 makes a huge difference however I still get these squibs? No bullet stuck in the barrel but it just explodes in the chamber.

The Tommy enterprise Mag sleeves were a bit of an issue, they don’t quite seat properly without a love tap and yes they are the proper fitment and secured tightly. The current video attached actually broke the mag sleeve.

I’ll post a photo in a comment below showing what’s happening to the shells when it just jams them rather than propels chambering the round. No idea if it’s just the ammo (Aguila interceptor) or if it’s too high of spring tension on the magazine or if I have an actual issue with the action.

Any chance those rounds are suffering from rim lock ?

Many years back I converted some Turkish SAP 6 mags to function in my Valtro PM5 ( shotgun stuff ). Quite often they would feed flawlessly, but occasionally I'd get failures to feed where it looked like the round being pushed from the mag couldnt get enough nose lift before getting jammed on the bottom edge of the guns feed ramp. It happened so seldomly and usually in a high stress situation (3 gun) that I never stopped to take a good look at it.

Years later, I happened to notice that the very modest rims of the shotgun shells were occasionally rim locking because of sloppy loading of the magazine. The top shell would be pushed by the bolt, but because it was half ass rim locked it would also drag the shell beneath it forward for tiny distance while also preventing the top shell to cant up as it clears the mags feed lips.

I started taking extra care in loading the magazines so that every shell was pressed in ahead of the previous one and the result: flawless function!
