M 18 and 22/32 hard ejection

[Protocall_Design]

Also, when reaming, you want to leave the extractor in, as it is part of the chamber. You do want to clean the space under the extractor and the bottom of the extractor well before starting. Put a couple of fired cases in other chambers to keep the extractor from moving sideways. Ream so that the seat for the rim cleans up on both the cylinder and extractor so they are both in the same plane.

No disrespect intended toward your gunsmith, but it's *possible* that his reamer was worn, just as S&W's reamers wear as cylinders are manufactured, eventually resulting in undersize cylinder chambers before they change their tooling. If that was the case, he may not have removed enough material to bring your chambers into SAAMI spec.

Please post the results of your own reaming when you receive your new reamer. I'm curious whether you'll remove much material since your gunsmith already worked on your chambers.

Some of the .22's I've done have taken quite a bit of work to bring into spec (lots of turns, lots of material removed) and some took hardly any time at all (very few turns, very little material removed). The good news is that all my .22 revolvers will now shoot ANY ammo I've run through them with absolutely zero extraction issues. This includes a bunch of S&W's, Rossi, Taurus, and Ruger revolvers.

Best of luck in your endeavor!

That was one thing I was thinking. When I get the new reamer we will know.

I got a M 18 and a 22/32 Kit gun (I frame) last year and when I shot them the empties were so tight I could not eject them …

Any suggestions

I’m thinking poor job of cleaning the revolver cylinders by the previous owners.

Besides 22s I see it a lot in 357s that had a steady of 38s fired in them.

You know I never had a problem in the 1960s to the early 2000s with the 22 revolvers and
shooting with my children and grandchildren. But I am really OCD about cleaning firearms.

So is this a current production issue with the revolvers or with the ammunition today?

had my kit gun and M18 reamed for difficult extraction. I took my son and grandson to the range over the 4th of July weekend and my started with the M 18 and it still would not extract and neither would the kit gun. Next week I took them back to the gunsmith and he looked and said they had been reamed, so took them home and tried really cleaning and polishing the chambers. No luck except with some Remington subsonic ammo. I thought, read a lot of posts about the problem and ordered a Masene finish cylinder reamer and some cutting oil. One by one, starting with the M 18 I took cylinder out of gun cleaned it and reamed. I dipped reamer in cutting oil and would give it 2 1/2 to 3 turns remove, clean shavings off by wiping with paper towel, brushing along flutes with a new, clean acid brush, then wiping again, then another dip in oil and enough turns to just kiss the extraction star. I then took it outside and sprayed with some brake cleaner then ran a patch with a little clp through each chamber. I loaded two different makes of ammo that had given problems CCI mini mag and some German Geco labeled optimize for bolt action rifles, a little faster than normal standard velocity and slower than the mini mags, alternating chambers. Crossed my fingers and toes hoping and they all extracted fine.

With the amount of shavings that came out of each chamber I really wonder if my local gunsmith actually reamed them or maybe his reamer was worn small.
Oh I had added one gun an old K 22, that I got back in late 1969. I had never had any problems previously, but when I tried some of this ammo last week it was difficult to extract so went ahead and reamed it.

Glad to hear you had a good outcome! I love shooting my S&W .22 revolvers, and they are so much more fun to shoot now that they extract easily.

I went back and did that.
