I have a switch barrel 700 the was origionally a 300wm. I bought a PTG bolt with a .473 boltface (not oversized). I trued the action with the PTG action blueprinting toolkit and lapped the lugs of the new bolt to the trued action. I use Criterion Remage barrels (the button-rifled division of Krieger). The Remage barrel is a remington 700 barrel that utilizes a savage style barrel nut and makes building a custon rifle truly within the realm of a do it yourselfer. My long action 700 is the host for .284 win, .308 win, 6.5x47, and 30-06. If you google search northland shooter supply, call the number and talk to jim briggs. He has a large inventory of remage barrels in different contours, calibers and lengths. He sells a .280ai match chamber that is throated for the 180 weight class of vlds and such. It allows max case capacity with heavy bullets and easily mag feeds in any longaction magazine. Food for thought.
