I think David addressed the Tenon size. But here is some data on the bolt head.

The 7mm PRC is a long action cartridge with a .532 rim. The WSM's and the 9/16" Bolt Head are for short actions and have the .532" diameter rim. The 9/16" bolt head requires a firing pin that is 1/8" longer than the standard firing pin in a short action with the standard 7/16" Bolt head. The standard BH length for a long action is 1/2" and would need to find an additional .062" somewhere. All LA calibers in my recollection where made with this length Bolthead including the .532 Magnums.

The 338 Lapua (.588 rim diameter) and the ultra mags(.534 rim diameter)may have a different BH length. I can't recall.

Hope this helps lead you to the conclusion you are after.

Is there any particular reason having the 9/16 Bolt head is important?
