RE: 338-06........what a shame.
I' m not certain what the status is of the .338-06....since weatherby chambers for it and also supplies ammo for it, it should be a standard round.....but I' m going to reserve that statement for now.
This much I do know...RCBS will send you dies, and most barrel manufacturers will send you " FTC barrels in .338-06
IMO it' s one of the finest " big game" and " plains game" cartridges a going.....I love it.
All you need is a new barrel to attach to any .270, .25-06, .280, .30-06, or .35 whelen, a set of dies and your off and running.
Approximate cost to convert your gun is about $400......give/take.
