I've got a 31" barrel chambered 264 tight neck that isn't as fast as I'd hoped, so I'm punching it out to 6.5mm STW or RUM, depending on which dies I can find without having to order custom. I'm not in a hurry, will likely shoot the throat out of the 264 chamber before I do anything. So, If I get them inside the next 2years I won't have to order custom dies. I'm in Canada, but can have them shipped to family in the US. Thanks, JT.
