What other calibers if any share the same bolt face as a .300 win mag for a barrel transplant? I am trying to get a flatter traj. with less recoil. Would the .264 Win Mag work?

I believe a 264 is a necked down 7mm mag so it should work then. I am going to see if my manual tells me.

if you click on the link I posted and look at the first result. It says the 264 and 300 win mag have a 540 diameter

Thanks, in one of the forums I was watching it said it had about the same diameter and that made me wonder a bit. Thanks for your help.

Re: Same bolt face as .300 Win Mag?
There are only three basic, widely distributed, boltface diameters:
.378" : .222Rem, .223Rem/5.56x45, etc family
.473" : 7x57, 8x57, 30/06, .308Win, etc family
.532" : All H&H Magnum family (7RM, 300WM, etc), Win & Rem Short Magnums, RUM's
There are some intermidate for 7.62x39, PPC's, 6.8SPC, etc and some larger for .416Rigby, Big Wby (.378, .460). Then .50BMG
For an easy swap to your .300WM, look for a cartridge with ~.532 casehead and COAL <3.40"

Re: Same bolt face as .300 Win Mag?
I believe that the .257 Weatherby Mag is the same as well. If you are after a hunting rig, this would fit the bill nicely out to 900+. It would also give you the laser-beam without much recoil.
