I have a DWA blued 22LR Monson with a 6" barrel that is beautiful and accurate, but after I shoot 6 or 12 rounds the spent shell casings are difficult to eject. I've thoroughly cleaned the gun and tried different types of ammo, but the same problem occurs. Is this a common problem? Anyone have any suggestions?
Thanks.

A typical cause of an extraction problem is a rough chamber surface. Take a look at the surface finish of the chamber walls and see if there are any tooling marks or rough finishing of the surfaces. Ideally, they should be mirror smooth. If they are rough and you want to eliminate the problem, the chambers will need a light honing. The other common cause of an extraction problem is an oversize O.D. of the cartridge case but I doubt that would be a cause in your situation since it is a .22. Please let us know what you find out and if you are able to resolve it. If you really want to have fun with it, read up here…….:-)

Possible that the chambers are VERY dirty. May need more than normal cleaning to clear the chambers of accumulated crud. Sometimes chucking the brush into a drill and power scrubbing works.
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Get a Hoppes Tornado brush and use with drill, if that dose not work take a
regular brass brush and wrap some #0000 steel wool on it and use drill.
Depending on how rough chambers are #000, #00 or #0 steel wool may
be needed.

Have the same problem with my 7445. With both the 445 and the 44 shells. Checked the chambers, and sure enough, the are rough about half way in. I'm going to try steel wool first. Good idea, thanks.

Back in the day dan wessons were pretty well known for having rough chambers and barrels. Obviously they aren't all that way but it isn't that uncommon either. That was one of several issues frequently mentioned by their critics. The barrels are an easy fix, if you get a bad one that won't shoot for what ever reason you just replace it. The chambers are not usually that hard to polish either if the gun turns out to need it unless you have an exceptionally bad case.

Must be a .22 thing, as the venerable S&W K22 has the same problem.

I have seen several K-22 cylinders ruined over the years by guys using drills to clean cylinders not realizing how much cleaning ware they were putting on their S&W's and eventually all had worn cylinders and real sticking problems. When you use the bronze cleaning brush manually seldom will you use more then two or three passes when cleaning, the drill will give two or three hundred revolutions in just a couple seconds. At that rate it's not but a couple cleanings until you have put a life time of ware on the chamber, so be very careful and use the proper hone and not some crazy idea of a drill and bronze cleaning brush to hone a cylinder.
My 722 had that same problem and when you used a proper light it was easy to see it was a rough cylinder and not a carbon fouled chamber. I sent mine to Kieth at DW to see if it could be borred out to WMR and a new long rifle cylinder fitted. Keith said the cylinder was bad enough it might not be able to be even honed to WMR, as a lot of those cylinders were bad enough that they could not even be machined out to a WMR and get smooth cylinders. Luck(?) was with me and I now have a convertable DW, that I will never use because WMR in a revolver is a waste of time and money.
The WMR will loose all that extra zip as they have no cylinder length as does a long rifle round and then when jumping the gap they loose most of their powder out the cylinder gap. If you crony a WMR revolver the speeds will in some ammo be subsonic, but you sure have a lot of flash bang. Winchester WMR white box Dynapoint in my S&W 48 (sold after testing) and my 722 were only running 1150 to 1200 fps range from either gun and S&W had IIRC a .0025" cylinder gap and my DW was set to .006 standard gap on first run and when gapped down to .003 it made no velocity difference in the WMR. IIRC the best we got out of any of the WMR was about 30% velocity drop from factory rated ammo from CCI. My WMR cylinder was replaced with new LR and the gun fired with several types of ammo and it all matched the WMR or slightly exceeded the WMR offerings and I also found that point of aim did not change when cylinder was changed. That alone told me all I needed to know. The WMR cylinder still sits in gun cabnet unfired since that test and as stated earlier the S&W M 48 was traded off.
