Breeching an older barrel

[charliek]

I am fitting the breech plug on a barrel which has been in the closet for some time. The question is which flat should go up? The barrel is marked "GRRW 32A" with a marker on one flat near the muzzle.
On another flat near the breech it is stamped "GR (with the R upside down) 8114". The breech plug is seated solidly, but the tang does not line up with either of the labeled flats. Is this a problem? Should I adjust to line up with one of the labeled flats and if so which one?

Well, I certainly would want all the markings on the bottom where you couldn't see them! :wink:

Sorry for the double post.

Most gunbuilders want the factory markings on a barrel hidden.
If the tang has to be rotated to accomplish that then so be it unless you really don't want to re breech the barrel.

Your the only one you really have to please.

Thanks, if runout is not likely to be an issue I can draw file the stamped marking out, its pretty shallow.

For an older barrel, I would definitely put the stampings on the bottom. Allot of older barrels had runout & the barrel is normally stamped purposely to have the barrel rotated for your benefit & stamping goes to bottom.

On newer barrels you seldom see runout & it may not be as critical.

Please don't think of this response as rude. Only thinking of your safety and enjoyment.

If you have to ask such a basic question, IMHO, you are not qualified to install a breech plug. Such installation is, perhaps, the most important and difficult step involved in rifle building. I suggest you send the barrel and plug to a qualified bp gunsmith with instructions where you want which flat and let them do a proper (and safe) job.

GRRW barrels were centered up, so no runout should be present. They called them "Plumb Center" barrels. They are very good barrels, so enjoy having one of the best! Good luck on your build.

This advice from one ol' feller to another.
