Squaring the action to new caliber after rebarreling

I hav noticed when I send an action off to get another barrel put on it in a compatible but different caliber from what it was originally, there is always a substantial cost ($250 or so) to adjust or square the bolt or action to meet the new barrel and caliber of choice.

Now I know headspace has somethign to do with it, but wht is really involved here. Is it complicated. What I am trying to achieve is to be able to order barrels and place them on my actions and do the other work out of my workshop.

I am not trying to be cheap, but I love getting my hands on and working with this stuff and just want to know how. It began with painting stocks, then replacing triggers, then bedding actions...I can;t get enough. I love it.

What tools are recommeded to do this? Any suggentions on how to measure headspace? I usually get my gear off of MidwayUSA. Do they carry what would be needed?

thanks,

Jim
 
It sounds excessive and unnecessary... unless you are changing the bolt face, a trued action/bolt assembly should require no work from barrel to barrel...

...now if that charge includes the labour for the new barrel install it is completely in line in my view...
 
Fitting and Chambering barrel to Your Action
(Includes Lapping and Truing of Action)

Yes, I guess it does include the labor and it makes sense. Thes work I hav gotten back from these folks is great and I'll use them again, at least defintely for barrels. If I can install them myslef with my vice and barrel wrenches, I would rather.

I guess the action on my Rem 700's are already trued, so not a big deal.

IS RECHAMBERING A TOUGH THING TO DO? Is that where measuring headspaces comes into play?

Thanks,

Jim
 
Re chambering is just that - rechambering an existing barrel that already has threads and a chamber... in some cases that can be more work than using a new barrel blank...

A barrel blank requires that a chamber be cut centered as best possible on the bore. The threads need to be cut concentric with this chamber and fit the action properly. The barrel needs to be fitted closely to the bolt, with the chamber ending up with the correct headspace, it needs to be crowned, the outside need to be polished or finished in some manner...

... none of this has allowed any time for action work which should be done first... action work however is not required every time a barrel is fitted.... done once correctly and it should be good...
