Blueing a barrel rifling and all

[meek]

Hi guys.

New recruit here

I have an old barrel I'd like to reblue.

Can anyone tell me, is there any problem if I just submerged the entire barrel, rifling and all in the solution?

I know some people plug the ends, but why not just do the lot?

Thanks
Meek

A few things...

1. Strictly speaking it bluing does add thickness to whatever you're bluing. I think it's something like a half of one thousandth of an inch... couldn't say if that has any appreciable impact or raises any safety issues due to reducing the internal diameter of the barrel, but there it is.

2. The internal of your barrel won't blu well anyway. Between any residual copper/carbon fouling it just won't take.

Basically it serves no purpose, and you're just adding something that the internal of your barrel doesn't need.

As you asking to achieve something specific? Or just skipping the work of plugging the throat/muzzle?

At best the blue would just be shot out as soon as you use it. Worse it could cause some unusual wear though and give you problems?

Best leave the inside of your barrel untouched IMO.

Sounds like lazy bluing to me

Potential to jam a bullet you reckon?

I couldn't say. Either way, it's not something I'd be keen to put to the test.
