Cutting revolver barrel

[Bob in Phoenix]

Attn Gunsmiths: OK, let's say I've decided to shorten my 7 inch barrel down to 5 inches. When the gunsmith cuts it, does he leave a little bit extra to allow for recrowning the barrel, so it winds up at the desired length?

To put it another way, how much is a cut barrel shortened when it is recrowned?

Thank you.

Bob

It's negligible.

That sounds like a question for who ever you plan to have do the work. Jim.

Speak with your gunsmith about how he shortens and crowns barrels. Odds are, it won't end up being a perfect 5.000", but will be plus or minus a little. Even factory barrels vary just a little.

If you 'turn' the barrel to length on a lathe, you turn it to length you want.

If it's a flat crown like Ruger barrels, then you just chamfer the outside diameter and the bore. So the length doesn't change.

If you want a round crown like S&W barrels you can turn it round on the lathe if you're good or use a crowning tool. But again, either way, it doesn't change the length (unless you go too far and remove material that you don't need to).

If you cut the barrel with a hacksaw, it won't be exactly flat on the end, so you cut it a little longer to leave enough material to square up the end, then crown it.

Every gunsmith has their own way of doing things. It depends on the person doing the work.
