New Barrel or Cut, Thread and Ream?

[yobuck]

Just to add another level of difficulty, this is the older intermediate action that had the barrel drilled/tapped from the factory for target blocks, which I'm using for my scope.

So, if I face the chamber end of the barrel, I've got to get one full revolution and not fractions of revolutions to get the blocks to align and mount my scope when complete. So, I'm looking at sinking the chamber 0.050". 20 TPI, correct?

I'm thinking maybe, I need to re-chamber similar to a non-savage rifle with the barrel installed in the action to get the blocks aligned. Or, face a little shy of 0.05", short chamber, and proceed slow, adjust as needed.

Anyone know how much clearance is permissible between the bolt face and barrel?

My FIL is the tool/die guy. Usually if he can't help me with these types of projects, it's because I can't sufficiently describe the need. We usually have a good time either way.

This $300 rifle is getting more expensive all the time.

Trust me, i do feel your pain as for using that fine old scope.
As you know i used one like it for many years.
But there does come a time when its just best to move on.
Are you complicating what might not be simply because of the scope?
And the scope blocks on the barrel were never a good idea anyway.
The good guns used a sleeved action or a barrel block for mounting those type scopes.

Scope isn't going anywhere. Thinking about sending another off to be serviced right now. If I get a new barrel, I'll drill/tap.

No shortage of minty take off barrels on Ebay. I have used many w/no issues.
