Hello, I have a SA remington action, .473 bolt face,,, currently the action is wearing a 7-08 barrel,,,,,,, I'm wondering what it would take to modify this action to one of the WSM chamberings, most likely a 270WSM, or a 7WSM. I know the bolt face will be opened up but I'm more concerned about the feed rails, I'm just tossing this around, I have not had the chance to handle a WSM offering from remington, I dont know what they had to do to the machining process to get the WSM's to chamber. If anyone has gone through this, I would love to hear the process!! Or if it should be done on a 5 year old rem. (concerning dimensions, not integrity) thanks for any info!
