Default Can a factory rifle barrel be re-chambered ?

Can a Savage factory rifle barrel be re-chambered ? from 243 to 6 mm BR or
6x 47 Lapua? I understand it will need to be shortened where it screw into to breach. Is there enough material to cut extra thread. Is it as simple as just running a reamer into barrel?

Can this be done?

It would probably be simpler and cheaper to get a new barrel in the chamber you want. It would not be a problem to switch back later if you wanted. Savage is very easy to swap barrels. Besides the twist rate for the 243 may not be optimal for the new round.

it could be done, possibly, depending on whether there is enough material in the chamber area when you change the chamber dimensions. but i agree with JTJ, it would be much easier and cheaper to buy a new barrel with the twist ratio to match the cartridge you plan on chambering it for.

Default Cost of barrel

The problem I have is I live in New Zealand. Barrel cost ? $250 USD export charge for a barrel $300 USD freight cost $60USD? 12.5% Tax at my end on total cost.

Ouch! Talk to a gunsmith capable of doing the work correctly and find out what it will cost you. I really dont see the benefit of either round over the 243 which is essentially a 6x51. I am guessing that you hand load and properly loaded the 243 is a very accurate round. The one my wife had was shooting 5 shot groups under .5 moa with hand loads of course. Several 1 hole 5 shot groups at 100 yards not much bigger than the bullet. Remington factory was under 1 moa. What is the length and taper of your current barrel? Hers was a standard taper but cut back to 19" so the barrel was short and stout. The stock was shortened to a 12" LOP as she is small and the rifle was sized to her on both ends. I had to go with a powder on the faster side and was using 100 grain spire points. Velocity was a little on the plus side of 2800 fps.
I googled savage replacement barrels new zealand and came up with several websites. Below is one link.

You gotta have a barrel maker in NZ that can do it cheaper?

I have a friend in NZ says, everything but mutton and earthquakes is
imported... or something like that.

Twist rates are the big factor when rechambering for any caliber.
