So, I'd like to build a left hand remington 700 6.5 creedmoor custom to be guaranteed at least sub moa. I've never done this before so I'm wondering, could I just buy any caliber left hand remington 700 and have it sent in to be rebarrelled? Or it probably has to be anything bigger than 6.5 mm? Then I buy a different stock if I like and have that same guy install it? What's the typical cost for something like this besides buying the initial rifle to begin with? Would this be a good route to getting a good precision rifle?
