First of all I have an older Remington 700 .308 semi heavy barrel, crappy fiberglass stock and somewhat worked factory trigger, not a bad rifle but it could be better faster harder. I know some 600-1000 yard shooters and the 300 is what they shoot. So i am pondering possibly converting my 308 into a 300 WSM can this be easily done by my local custom rifel shop? Do i need a new bolt or can the stock bolt be bored out to accept the bigger case? Do they make a bolt that i can "drop in" made for 300 wsm? Would that be cheaper than having my bolt bored out? What is the barrel life like with the 300 WSM? 1000 rounds 3000 rounds? maybe more?
