I know this is a long shot. I want to trade my Kimber 8400 S/A mag bolt for a 308 bolt. Mine is off a Kimber 8400 270 WSM Classic. Would like to keep the action and do build with the smaller bolt face. I will also throw in the magazine, follower and follower spring. Kimber is bull headed about selling parts. They told me I could get a bolt by buying a whole rifle, I wasn't amused.
