Me again with feeding issues. The problem is a Norinco copy of the Browning semi-auto .22 . When I load the tubular magazine, then #### it, the gun feeds two rounds at once, causing a jam. If the jam is cleared, it seems to function OK for the rest of the mag. The problem seems to come from the cartridge stop or cartridge guide spring, but so far I have no luck. Any ideas other than not buying a Norinco from Lever Arms?
Thanks,
Geoff
 
It may be a silly question but how does it work if you load less than a full tube? I am thinking it may be too much pressure from the spring when the mag is full.
 
I sold two of these through my business; never brought any more in, those two were enough. Had to fiddle with both to get them to feed. Polishing the feed ramp that guides the bullets into the chamber made a difference. I wonder if the first round is hanging up, and this is fouling the next one.
 
Thanks, guys.
I have tried it with a full mag (10) as well as only 3 or 4 rounds, with the same result. I will try polishing the feed ramp to see if that helps. The whole thing is pretty rough inside, so maybe some smoothing will help.

Check that the disconnector/interrupter thingy on the upper side of the receiver is in place, above the bolt. It controls the mag feed, allowing the next round to be pushed forward when the bolt cycles. It's easy to miss when reassembling the action, and I suppose it could get broken if force was used. The little part runs in the slideway on the top of the bolt.

Check over the bent wire spring that the cartridge rests against at the front of the mag tube, as well. I have polished the ends of a couple of them, using a Dremel and the rubber Cratex type wheel and a buffer. It seemed to help.

Put a radius, or at least break the edge on the chamber, where the round slides as it is pushed forward when feeding. Last one I did, I did with a cheapo electric fish hook sharpener, and it worked very much better. Without the radius, it was either shaving off great bloody chunks of each bullet, or just hanging up . Not your problem, but a heads-up.

I replaced an extractor with a Browning one. One of the two hooks broke off after maybe 15 bricks of ammo went through it. We'll see how that works out.
It fit fine, and the $20 it cost me, saved me from having to make one.

Success!

After a little smoothing and a thorough cleaning, I took it to the range today and it worked very well. Over the next while, I will try out different ammo, and if all works OK, it will appear on the EE at a very attractive price. Thanks for your comments, guys.
