i recently ordered a single shot savage action from northland shooters it is a 308 bolt face, what are my options to get this converted to the 300wsm magnum bolt head, some are saying the baffle needs to be changed also other than the bolt head, never been down this road before, any suggestions will be appreciated.what is the reason for the baffle to be changed. and can the stock 308 bolt head be bored out for the 300 wsm, please fill me in
