Redhawk, all of these things you say are true as we do not own this site, but are allowed to use it IF we abide by the rules of this site.
Concerning the original post, it is not practical to re-chamber a round to an AI version without setting the barrel back so that the headspacing will be proper, & you have a "crush fit" for head spacing. So, there is no best gunsmith for this as a good gunsmith won't do it. To use this barrel, you would need to go to a chambering like the 257 Hawk, which is longer or a version in 257 like the 280JRS.
I will bet that the Pro-Hunter barrels will be available in 25-06 AI in a year or 2 at Fox Ridge Outfitters. If not, I am thinking about buying a 7mm08 barrel & re-chambering to 280AI, again to avoid the problems of buying a 280 barrel.
Redhawk, I made this entry only for the sake of mentioning to someone who may look at the first post & wants to re-chamber a 25-06 barrel to 25-06AI.
