Hello to Weatherby aficionado's out there,
(This is posted in the gunsmith forum too.)

I am considering doing a custom build on a Mark V action, chambered in 300 Winchester Magnum. Here's what I want to acheive:

1. Find a used Mark V action with a 257 - 340 (magnum boltface).
2. I plan to fit a heavy barrel on the new rifle. So, I will search for a used #3 or #4 contour inlet Weatherby stock - preferably a Euromark. Now, I understand that the #3 and #4 inlet stocks usually were, and are, reserved for the 378 through 460 Wby Mags. So my question is: could a standard length Mark V (257 through 7mm) or even a magnum length (300 or 340) Mark V action be inletted into a #3 or #4 stock? I don't mind doing some additional glass bedding and inletting work to make it fit, but do want to avoid performing a hack job.

Lastly, for anyone who has a #3 or #4 contoured stock, can you tell me what the inet barrel dimensions are? I would like to see if a Remington Sendero-sized barrel would fit. I will probably have a Hart or Lilja barrel fit onto a trued and squared Mark V action.

Any insight will be greatly appreciated.

thanks,
Jason

Honestly,If your planning a build from the ground up,don't worry about the barrel channel dimensions as you'll have to measure and hog out the channel accordingly.The items you are looking for are not that easy to find,relatively speaking.My good friend lost his father recently and he was given a few mint condition weatherby mark V's with top zeiss glass on um'through inheritance .We looked at what could be done and in his best bet,figured they were all worth more in stock form.He ended up building a 700 IIRC,goodluck and Goodshootin'

I'm reasonably new here so I'm limited in what I've seen, but in all that I've read here and on other sites I've never seen anything custom built on a MkV action. I've read of people building on a Howa, which I believe is the same as the Vanguard action but never on a MkV.


You may have a really hard time finding the parts to put this together.

(and if I'm wrong hopefully this post will bring out someone to give you the answers you need)

Thanks for the reply Reagan.

The reason I am asking about the stock channel dimensions is to determine if there is enough width to fit a Remington Sendero - contoured barrel onto same. I don't mind carving some wood out here and there to make it fit.

I am not worried about the value being greater in stock form. It's for hunting and I plan to keep it.

XTR,

Thanks for the reply. I have a Vanguard action, and it works fine, but I realy like the Mark V. Between the short bolt lift (54 degrees), smooth, strong, 9 lugged action, it's almost indestructable. I've noted used Mark V's, perhaps with worn out barrels, on sale for around $500, maybe a little higher. But compare that to the price of a used M700, and it's a good value. The stock can be found at a couple of 2nd party dealers. The only question would be finding the #3 or #4 contoured stocks with AAA wood. That might take some searching, but well worth the wait!

Jason,
Generally speaking the barrel(unless straight/no taper)is usually as big in diameter as the action or sligthly smaller.Meaning the sendero barrel contour will be slightly larger but only by a little than the original barrel channel,again hog out the channel as needed for a good gap,keep the barrel free floated.Reason i said it was worth more stock,was the fact that most have never heard of anyone selling a weatherby markV action alone.As they are typically complete rifles only to be found.
I've always said to build what floats your boat,so all the luck to you.Goodshootin'

Thanks Reagan,

I don't expect to find a stand alone action, but have found many old and well used complete rifles online reasonably priced. That's my in. I was chatting with a guy on the Weatherby Rifles forum and he accomplished exactly what I propose, except he found a standard #2 inlet barrel channel would accept a Sendero contoured barrel with some inletting modification. But it can, and by all accounts has, been done.

Good shooting!
 
Re: Weatherby Mark V build - need some help out there

I had a custom built on a MKV. They are however, really heavy, and not the ideal platform to build on. Especially for the standard Magnum class of cases. They make a good 338LM cartridge class action. But still not great.

They are quite different from the Vanguards (Howas). Contact huntinfool18 here, as he has done them. He can point you in the right direction.

Thanks brand692,

I've used a Mark V rifle before (340 Wby) and never noticed any major difference in weight compared to, say, a M700. If anything the extra action weight would allow for a more balanced rifle. The weight savings will be in a barrel. I'll probably order up a fluted Sendero contour from Hart. Fully decked out I predict her to weigh in no more than 12 lbs. Not bad for a mountain/plains rifle.
