    Got a 300 Weatherby MK V Delux for free!!!! The catch you ask?
    It was bought out of a estate therefore some idiot removed the bolt.....!!!
    Anybody within South Africa who can assist me in making this beautiful gun whole again or do I have to import from the states?

    I would contact Weatherby customer support and see what they can tell you.

    I know that here in the states that you can not just purchase a bolt, it has to be fitted at the factory.

    Good luck dealing with the idiots at Weatherby, the two times I have dealt with them made me want to drive to California and bull whip them. Once was as simple as trying to get a thread protector for an accumark so I could remove their hideous muzzle break. I bet trying to get them to build a new bolt would take a letter from the pope.
    +1 with Brickburn on the boat anchor.
    Good luck.

    Try internet search (Numrich, Jacks First, MGW, etc..) If you find one find someone heading over there soon or one of your guys heading here in January for the shows and have them take it back to you.

    Wouldn't think a replacement bolt should be too hard to come by. It will need to be fitted by a competent gunsmith and he may well be your best help in finding what you need.

    Good luck.

    I did a quick search last night and couldn't find one.... SHould not need to be fitted, it's a mass produced item, like a car engine. It MAY have to be built up, meaning bolt body and firing pin, extractor, etc..... That would almost certainly require a gunsmith.

    In case you don't have it, I went to Weatherby's website and downloaded the owners manual for the Mark V and attached it. If you refer to the exploded view diagram (need a better name for such a drawing on a firearm) on page 17 and then look at the parts list on page 19, you'll see the bolt is made of of 21 parts. So, I wonder if Weatherby sells all the individual parts and then wonder what the total cost for that might be.

    May well be available as and "assembly", but getting it to South Africa could take some doings.

    They will sell everything in the bolt to a end consumer but not the bolt itself. I don't know of a rifle manufacture that will sell the bolt but they do require that you send them the whole rifle for them to fit it. I believe that is is something along with the product liability issue.

    If you do find a bolt you will need to have a gunsmith mate it to your rifle and check the head-space on it. It isn't as simple as just taking a bolt out of another rifle and putting it in yours or they would sell you the whole assembly.

    Ah, the joys of a Blaser R 93 and R 8. They WILL sell you just a bolt and they're interchangeable in the respective models; no need for a gunsmith to fit them.

    OK, guys, I am a gunsmith, and I have a question:

    Mass Produced firearms, (Or anything else) - production line: Everyone talks about "head space" so just out of curiosity, just how does one adjust "headspace" via the bolt of the rifle? Headspace is in the CHAMBER which is part of the barrel, Cartridges do no HEADSPACE on the bolt face.

    The Liability issue (I've actually seen this one!!) Is where a guy has a short action 308 (.473 face) and replaces the bolt with a .223 (.378)
    The issue is with the face size and the cartridge being fired.

    EDD: Contact me via PM, Let me see what I can do, if anything.

    My understanding is that they manufacture the barrelled actions and bolts, then using a go/no-go guage try bolts untill they find an appropriate one. That is then the bolt for the rifle.

    Head space is the distance from the bolt face to the place where the cartridge meets the chamber. All bolts are not the same, you have manufacturing tolerances therefore your replacement bolt will need fitting. As a Gunsmith you should know this. To adjust head space you must turn the barrel in and recut the chamber.

    And you've repaired haw many rifles in your lifetime? Replaced how many parts?? Test fired how many weapons???
    Adjusted headspace on a rifle how many times?
    Been gunsmithing how long???

    AR Style/tactical rifles, YES, because the barrel is not screwed in, it's screwed ON, and the MILSPEC tolerances it could be an issue.
    Bolt production guns, no, because is you screw the barrel in or out to adjust the headspace, you change the orientation of the barrel markings. The when dealing with a used rifle, if the lettering is not lined up, take a HARD look at the riflem because you don't know what someone did to it.

    I had a new bolt put in a Remington model 700. Sent it to Remington and they did the job.

    It's not the number of times you did something ...but the knowledge to do it correctly ........am I wrong ? Seems headspace gauges kinda need a bolt to work ....why do they make them ? If the bolt is not required ?

    Were the MkVs all made in Germany or the states?. If your MkV was built by Howa in Japan maybe they could help,(just a thought). I did an E-bay and a Gunbroker search and could't find anything

    OK, Since you have the "knowledge to do it correctly" you tell me. Where and how is the headspace "adjusted"?

    I'll enlighten you, it's where the barrel screws into the receiver. To adjust the headspace the barrel is screwed in until the bolt closes on the "go" gauge. Then the "no-go" gauge is inserted and the bolt should not close. When you do this, I've had the best results with the extracter removed so the gauge is set square and flush on the bolt face. Yes, I've had them where the owner attempted to do it himself and told me the headspacing is "off" and everything checks out fine.

    On the belted magnums (I own three) there is ONE gauge for all - this is why people say the "headspace" is set on the "belt" - yes, it is, however if the chamber is not cut true there could be issues with chambering a round - but that's not "headspace".

    Barrels are tough to get off (typically) and most rimfires that I'm familiar with, the barrel is not screwed in/on (except Ruger 22s) the are pressed in and pinned. Savages have the external nut that requires a special tool and I've had them where either the barrel is screwed too far in or the nut is cracked because someone decided to apply excessive torque.

    Action blocks are specific to make and model for a reason, too much torque trying to unscrew the barrel and you twist the action and it's ruined; too much heat to get the barrel off and you ruin the action.

    Let the barrel slip in the vise and it's scratched deeply.

    Again, on a slip on/in barrel (AR platform) and a 2 piece bolt, ABSOLUTELY, for replacing a bolt in a bolt action rifle you can check the headspace, however, IMO on this weapon you're wasting time and money. If it makes you feel better and helps you sleep at night, then by all means buy the set and check it. Probably you'll use the gauges once in your lifetime unless you decide to replace the barrel.

    Numrich Gun Parts in New York does list the bolt assy complete however they are sold out (and I'm not sure of their ship overseas policy). https://www.gunpartscorp.com/Products/1614920.htm

    Screenshot (278).png

    If I were headed to SA, I would find a bolt and deliver it to this guy, and I'd check the weapon and I'd test fire it. Then I'd measure the fired case, but, given the original symptoms (Owner removing the bolt and misplacing it) I'd have no problem getting this rifle up and running. Just need the serial number to verify which model and caliber to ensure the weapons is as originally manufactured.

    from Brownells website:
    Determine Correct Headspace
    With the exception of the .240 Weatherby Magnum, most belted, magnum cartridges are based on the .375 H&H Magnum case. Therefore, they all use the same headspace gauges. The following is a partial listing of those cartridges which use the same Belted Magnum Headspace Gauges: .257 Weatherby Mag., 6.5 Rem. Mag., .264 Win. Mag., .270 Weatherby Mag., 7mm Rem. Mag., 7mm Weatherby Mag., 7mm STW, .300 H&H Mag., .300 Weatherby Mag., .300 Win. Mag., .30-.338 Win. Mag., .308 Norma Mag., 8mm Rem., .338 Win. Mag., .340 Weatherby Mag., .350 Rem. Mag., .358 Norma Mag., .375 H&H Mag., .416 Rem. Mag., .458 Win. Mag.
