Thanks J E Custom. I have looked at a few but never had the chance to work on or inspect one.
Interesting lug contact area. With 3 lugs in one diamter and a few thou clearance, each lug is what, .44" long ? and .062" into the action [clearances reduce the actual contact area]. This would give .240" total lug contact area, that's a LOT of contact area, well over 2.5X that of a Rem. I'm not going to run out and buy one or anything but its interesting nontheless.

Weatherby MK5 bolt dimensions =

Lug O.D. = 0.845 with 9 lugs.
Bolt face O.D. = 0.716 avg.
Bolt face I.D. = 0.537 standard magnum.
Bolt face I.D. = 0.585 378 based cases.
Magazine length = 3.800"
As you can see with a bolt face outside diameter. of .0716, you can open it to .0585 or even
.0610 with out removing the shroud.
I hope this helps
