    1.) Two cartridge families: 240-257-7mm-300-340, and, the five 378-based carts.
    Do they use the same Mark V action or is there a difference in actions besides
    the bolt face diameter ? Is there a "short" and a "long" action version ?

    2.) What is the diameter of the action(s), or, the max diameter of the barrel
    at the big end ? I know the Rems are 1.200~1.250.

    Trying to get an idea how much bigger/stronger they are over the Rems.
    Going to start a Weatherby project and need to know what is what.

    The .240 Wby is not in the same cartridge family as the .257-.340 Wby family. The .240 Wby uses a standard diameter bolt face (.473"), whereas the the .257-340 uses a magnum bolt face (.531").

    And yes, the .240 Wby uses a different action than that of the .257 Wby and larger calibers. The Mark V chambered in .240 Wby (and all other standard cartridges, such as .270 Win & .30-06) uses a 6-lug bolt and action.

    The .257 Wby and larger calibers use a 9-lug Mark V action.

    Weatherby Mark V barrels are supposed to be 1.060" shank.

    What caliber are you looking to build? If it's a 338 Lapua or 378 Weatherby based then the Weatherby is the easy choice. Most everything else will fit fine in a Remington. Either are capable of fine accuracy.

    there's also the older Weatherby Varmintmaster action. Rare as hell, and I think I've seen two or maybe three in my lifetime. The action is shorter, and came in either 22-250 or .224 WBY. I've seen exactly one .224 in my lifetime. The round is kinda like a belted rimless and belted Wasp that's been stretched.

    Thank you Gents !
    For some reason my reply didn't post, anyway, I am going to build a
    long barrel 338-378, I figured to use either a Mark V action or a custom
    action. If I have to buy a whole donor rifle just for the action, then
    I may be into a custom, just the way the $$$$ work out.

    Long term build.

    I suppose any barrel maker has blanks that are 1.300~1.400 diameter
    (or whatever the Weatherby action is), I assumed they are bigger
    than the Rem.

    If your going that large and possible custom,youowe it to yourself to do a search on here for a 338 AX or Allen mag.I am a Weatherby fan also,took most my game with a 340 Wby

    While mostly true that is not entirely correct, some rifles were made on 9 lug actions with a .473" bolt face. Specifically I have a Mark V Deluxe 9 lug 30-06 made in Japan (1973-ish----1994-ish).

    Sounds like I might likely be safe picking up a donor rifle in any caliber
    except 240, in a Mark V that is.

    Are the synthetic stocks all solid, Weatherby doesn't use any cheap
    hollow plastic stocks do they ?

    Then your best bet is to find one with the 378 bolt face.
