What's involved in rechambering a rifle?
A busy mind is always occupied, or so they say. Well, my busy mind keeps turning to the 6.5 Swede; I want one but can't decide whether what I want more is a mil surplus rifle or a heavy barrel tack driver.

Anyway, my question is this: suppose I decided to have one of my other toys rechambered in 6.5 Swede - what goes and what stays?

Is it a worthwhile exercise or is it simpler just to go out and buy another rifle?

Pete---

The first question is what rifle do you have to rechamber? Or, are you thinking of re-barrelling?

To rechamber the 'smith pulls the old barrel and tries to set it up so the bore runs true.....a LOT of factory rifles have a chamber mouth out of concentric with the bore.....and then carefully ream to the larger chamber and reset the headspace to the new caliber. Reinstall and test fire.

I always suggest recrowning while the barrel is off and a complete cleaning if needed.

You can re barrel a Masuer without a lathe.
The Walsch book is very good.

Or you can buy a lathe and build tooling like I did.
More and more refinments and improvments to the operation can be added.
Keunhausen is not a very well written book, but it gives some of the objectives of building that tooling.
