I've picked up a used 6.5-06 barrel and a Rem 700 LA with a mag bolt face. Is it possible to rechamber the barrel to 6.5WSM or is that too far to set the barrel back?
pointer..........I would just stick with the .264 if I were you.......the parts you have on hand are going to make it a snap , and there's nothing the 6.5 WSM will do that the .264 won't do . Your barrel would have to be set back so far to rechamber to WSM it may not be feasible . The .264 will feed from your long 700 , the WSM case may not .
The .264 really is a nice cartridge ; much better than it's detractors would have you believe .
P.S......the .264 and a 6.5/.338 would be indentical .
If i am not mistaken the .338 case is the same case as the .264 Win Mag. I don't think the 6.5 WSM will do anything that the .264 won't do other than come in a shorter action. The 6.5-06 will come a distant 2nd with 140 grain bullets. Good luck with your project. sounds like a lot of fun
