Chamber Honing
Chamber Honing
Chamber honing polishes the inside walls of each cylinder chamber to a smooth, consistent finish. Factory chambers come off a reamer with tool marks running down the wall. Those tool marks grab brass, especially on hot loads or sticky brands, and they make extraction feel gritty. Honing smooths the walls so brass slides in and out cleanly on every shot.
What This Add-On Includes
-
Precision hone through each chamber to remove factory reamer marks -
Uniform bore finish across all chambers so every one feeds and extracts the same -
Verified fit with a range of cartridge brass before the gun ships -
Pairs well with chamfering and moon clip machining for a full reload-speed package

-
Cleaner extraction, especially with hot loads or sticky brass -
More consistent shot-to-shot feel -
Less scoring and drag on your brass, which extends the life of your reloads -
A subtle but real upgrade that a serious shooter feels immediately

FREQUENTLY ASKED QUESTIONS
-
Federal or Remington & others makes works the best with the .025 thick Full Moonclips, which fit all the .38/357 standard moonclip. They allow the cartridges to have some movement or wiggle so that they will fall right into the chambers once properly aligned. Winchester brass does not work at all as the groove width is too tight/small.

-
There is no SAAMI specifications for the extractor groove and each manufacturer makes them as they want. The following list gives you a great example. This is why the diameter size of the brass is critical to proper loading, unloading and fitment. Cartridge diameter too big and moonclip too small causes the moonclip to bend. The cartridge should rotate within their respective place and wobble slightly when all cartridges are loaded.
