rechamber

[huntwithme2]

is it a long and costly job to rechamber a tikka 30/06 left  handed into a 240 weatherby or a 300 win mag into a 257 weatherby

Its a rebarrel.. The caliber changes are fairly closer..

When you rechamber only you must stay with the caliber the barrel is. The only round you mentioned that you could rechamber to is the 300 mag. To do the others you must rebarrel the gun. BUT, with a 300 mag. you would have to alter the bolt face for the larger case head of the 300 mag. If your talking Savage it all easy, but harder on other actions.

Yes!  You would have to drill out the larger bore barrel very carefully and insert a liner in the caliber you desire and chamber the liner. Re barrelling to the new caliber with a whole new barrel in the new caliber would be greatly much less costly and quicker and more reliable. The first process is done in guns where the markings on the barrel need to be preserved. Otherwise, silly.

Any good gun smith can get a barrel of the quality you desire and chamber it and install it. Cost  varies first with the quality of the barrel and then the overhead of the work shop.

.240 Weatherby is basically a belted case 6mm / '06. Fairly easy in a gun already '06. I believe the .300 Win and .257 Weatherby use the same head/rim, again, rebarrel, no problem. As I recall the Weatherby is a bit longer. How long is the original action? Ask around at the range. Many men with machinist training do this sort of thing in the basement or garage.  Luck.

I don't believe one can reline to a high pressure round.. If it is possible do you have someone who does this?  Most relines are for very low pressure rounds..
