I was talking about custom rifle makers, not Dakota.
I was asking why would a barrel for a Dakota caliber be more expensive, which isn't manufactured by Dakota itself. Is there something special about the cartridge design? Does the bullet havean odd diameter? What is it?

The ammo could cost more if it's only made by an elite company, but an amateur gunsmith wouldn't need to charge extra for a barrel in a certain caliber, right? That's like saying a .300 Win. Mag. barrel is going to cost more than a .30-06. The price of the bullet is irrelavent to the barrel price,right?
