Finish reaming K22s, or, How To Solve Difficult Extraction In .22lr S&Ws

I have a 1952 K-22 that is mildly tight but useable. My problem child is a 4-screw M-48 that is unusable after 2-3 cylinders of ammo, at best. I suppose the .22 mag would be a different, longer reamer, eh?

Yeah, the 22 mag is a longer reamer, just as you suggest.
I'm not familiar with the M48 - is that a K-frame?
 
Great Thread

Interesting thread and very informative.

I had both a Model 17 and a Model 18 in my LEO career. I thought that they would really be good practice guns to simulate my Model 19 belt gun. Both would become unshootable after 30 rounds or so. Both went down the trail. I wish I would have known the above info 45 years ago.

I recently bought a virtually unfired Model 17-3 circa 1971 and guess what? It is a dream to shoot. No issues at all with easy extraction after close to 100 rounds. Wish I would have had this one back in the day.
 
Acorn? Where is the reamer? I picked up a K22 that needs some attention, so now there are a couple of us who need to use it...

Is the reamer accounted for? I used it and sent it along.
Just don’t want anyone thinking I kept it.
 
Reamer Handle

FYI, the Brownells forcing cone cutter handle is a perfect fit for the mentioned Manson .22 reamer. I found that I saved about $40.00 by not having to buy a new reamer handle.
 
I've got a question here. I've got a Model 17-5, 6" barrel. After cleaning, when loading, all six rounds drop in effortlessly, and eject easily. After loading four or five times, I notice it is more difficult to eject.

As a test, yesterday, I ran a brush through each chamber, and the gun was good as new, for a while.

I cleaned it last night, ran the brush, then patches through the cylinder, and earlier this morning I ran a "foam pad" with a few drops of Hoppe's oil on it, then took a photo. To me, visibly, it looks like the chamber has one diameter for the length of the case, and perhaps has a tighter diameter for the rest of the cylinder - but this might just be an optical illusion?

At any rate, if when the gun is clean, new rounds drop in with no effort, I don't think I would want to use a reamer on my cylinder. It sounds to me more like a dirt/debris problem, which is instantly fixed by running a wire brush through each chamber, bringing things back to the way they were after cleaning.

This has happened with CCI ammo in the past, and with Eley bulk 22 ammo yesterday - but again, I had no problems shooting, just running a brush through the chambers if things started to feel "tight" again.

I'll post a photo of the back of the cylinder after cleaning.

I had the sticky chamber problem and bought the reamer from Brownell's a few years ago. No keeping my shop well organized I ended up buying another reamer for my next revolver. I highly recommend this solution.

Lots of cutting oil and go slow. Proof is in the pudding as they say. Today I shot a Steel Challenge Match that requires 39 reloads. Not once did I have a case stick in the cylinder.

It's been working like that since I did the job.

It also helps to find the right ammo. I use Federal HV and even though it's lead with lots of wax on it I have no problems. I also use CCI BYOY which are plated. They go in and come out even faster.
