Lengthening chamber on Winchester 101?

[CoryTheCowboy]

Hey folks,

I have a Winchester 400 (for all intents and purposes, a 101) and I was wondering about having the chambers lengthened to 3". I know Winchester built the 101 with 3" chambers, so I don't foresee there being any problems with the action being strong enough. Or if they see a potential problem with this that I don't? I know I don't need a 3" chamber, but it would be nice to have.

Just wondering if anyone could recommend a 'smith in Canada that could do this job?

Thank you,

Cory

not a good idea.

The 101 was (always?) made with chrome-lined chambers and bores. If you try and ream the chambers, two things will happen:

1) The chrome plating will dull the reamer prematurely.
2) You will flake the chrome lining and it will start to flake/peel from the throat toward the muzzle. Not good.

To find out if your 400 has chrome bores and chambers degrease an area near the chamber mouth and put some cold blue on it. If it takes its not chrome lined.
