Winchester M70 Super Grade Rebarrel

[MTHunter1321]

I have a 300wsm that I’m considering a barrel change on. My question is would it be possible to put a Proof carbon fiber barrel on the existing stock / action? Or would I need additional parts? I’m completely green when it comes to gunsmithing, hence the question, and would have a smith do it, but just curious from those of you who know a hell of a lot more than me if it’s even a possibility.

They would more than likely have to open up the barrel channel.

If the action is a controlled round feed vs one of the push feeds you at the very least would have to have an extractor groove cut into the barrel.

You can definitely put it on the action, but typically those stocks are too slim for even their sendero light. You’d probably need a stock along with it.

You will need a new stock if trying to put a Proof on. What year is the M70?

Bought it new in 2010

Ok. Any good gunsmith will be able to rebarrel. They will have to cut a notch in the barrel for the extractor that the M70 has so it will probably add a bit to the cost. It will be easier to find an aftermarket stock for the more recent M70 rather than an old one. It's possible the barrel channel could be opened up on the stock. Is it a wood stock? Do you want to keep the existing stock?

Yes, mine is a wood stock and ideally would like to keep it that way.

You'll need to measure corner to corner on the forend to see if it will take a proof contour. Probably not. I'll pull a measurement off a proof barrel where it sits at the end of the forearm when I get back to the shop.

Awesome, thank you!

1.055" at the tip of the forearm. You'll want about .040" over for free float.
