Do you know any good gun Smiths? I would like to get a PTG bolt to cut down on some of the slop. Not sure what brand of barrel I want. If I go with the .30 cal I want a 1/11 twist and throat for 190-210 VLD. Not sure how tight to make the neck. How much to: fit the bolt to the reciver, pin recoil lug to reciver, taper, cut flutes in the barrel, crown and barrel the action?
