22LR what feeds and extracts reliably?

Post by plinksterman » 11 Jul 2019, 10:16 am

I have a Ruger American 22LR with laminate stock. It jams on feeding 3/10 times. One my friends has a ruger american synthetic that feeds reliably (be it with lucky13 25round or ruger 10round). I was confused, now I think I have it all figured out. The laminate stock has a magazine well that has been cut out by a router / wood mill. You can see the rounded indentation in the corners like pic related

. Whereas the plastic stock has the magwell of plastic based on the size of the injection mold. The difference is the plastic stock magwell is precise sized due to the injection mold. The laminate stock magwell is roughshod because they just haphazardly buzz it out with some cnc router piece of crap I assume, and it cut it too big.

Now the ruger mags dont mate with anything near the feed lips, they are held in 2 contact points one in the middle at the front, and again at the back. and the mounting points are round so the mags gan roll left and right until they hit the sides of the magwell. The greater the magwell is oversized the futher the mag can roll.

The top of the mag has the ejector and the feed ramp built into it, and the bolt slides over it very precisely, any roll and the bolt will strike it and jam against it rather than slide over it if it rolls around right/clockwise (rising the left side with the ejector into the path of the bolt). Or if it rolls around left/counter clockwise (rising the right side with the feed rampy bit) then the 22LR jams after feeding halfway and then the bolt crinkles the 22LR into a boomerang shape.

Basically, it is being a piece of crap for me, working smoothly sometimes and jam-o-matic other times until I figured it out. Changing or modifying the stock to more tightly hold the magazines in the EXACT right location will fix this. Don't know how, maybe build it up with araldite / cotton fiber, or solder, and then file that back until it fits tight and correctly aligned. That's my idea but don't know how I'm going to do that.

What 22LR feeds and ejects reliably and never jams not even once?

Besides a revolver or a single shot. Like whats the Lithgow with the removable magazine, or the Henry lever with the built in tube.

I have two Ruger Americans, and the RPR, and they all feed reliably. The Target model had issues when I swapped it into the MDT chassis. The mag well in the chassis is cut very slightly too long, allowing the front of the magazine to drop about one millimeter during feeding, causing feed issues. Holding the magazine up when cycling the bolt fixes it, but I found that increasing the length of the bolt through the middle of the mag, just slightly by unscrewing it a couple of turns fixed it permanently. I have many thousands of rounds through both the Americans.

I really like the non-rotary 15rd mag that comes with the RPR, it's excellent.

As for other rifles, I only really have feed issues with the Norinco JW21 lever when it starts getting dirty after a few hundred rounds. My Henry lever and 1950 BSA Sportsman 5 feed perfectly. I converted my 1940 Remington 510 single-shot into a ten-shot repeater, and it will do ten-round mag dumps with zero issues.

Have you tried different mags, i have seen a bad mag or two that just wouldn't feed right in certain Ruger models.

There is a Ruger mag mod described on the Rimfire Central forum.
Original mag supplied with my RAR fed fine, bought a spare clear plastic mag [Ruger manufacture] and it would not.
Mod involves shimming the mag to tighten fit fore and aft, I used silicone adhesive and brass shim.
You may find that your mate's mag feeds fine in your rifle, I recall once swapping CZ mags with a friend at the range, my mag fed just fine in both rifles but his gave trouble in his rifle but worked fine in mine !!!

I know it sounds stupid but could you just add a few layers of duct tape to both sides of the mag might be an easier fix

My cz 452 has never missed a beat.

Thousands of rounds and the only problems have been operater error.
Gun control requires concentration and a steady hand.

Maybe give one of these a go. I bought one for my 10/22 from cleavers a couple of years ago and its great. It might line up the magazine correctly for you
