Thought this old thread might help some folks who are on the fence about reaming their 22 cylinders: .22 chamber reaming report

It really isn't that difficult.

The root cause of this issue continues to be S&W using either: 1) undersized cylinder finishing reamers, or 2) "overusing" their tooling, until it is worn down to the point where it is leaving the cylinders undersized.

I've run my finish reamer through "several" S&W 22's, in some cases very little material was removed, in some cases a LOT. I attribute the instances where I had to remove a lot of material to S&W using over-worn tooling, until someone presents me with a more probable theory.

BTW, it's been stated by others, but it bears repeating. Finish-reaming a .22 cylinder to SAAMI specs does *not* degrade accuracy. The finish reamer pilot does *NOT* remove any material from the chamber mouths. Whatever your chamber mouth dimensions were before the reaming will be identical afterward.
