I don't have them all but I will give you the dimensions I have.
Weatherby MK5 bolt dimensions =
Bolt body = 0.845 outside diameter.
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
