Build a 7mm Weatherby mag

[bearpaw]

I have a Weatherby Mark V 7mm mag 26" barrel, that is in need of a new barrel and stock... Got to where the tightest groups I can get are about 2" at 100 yards with the occasional flier that may miss the target... 2 years ago I had the gun checked out by a smith, bore scoped the barrel and through it all... He said it was shot out and the stock developed some water issues over time... Not surprised by either of these things... He showed me on the screen, a lot of the rifling missing and the internal stock issues... I'm happy with the trigger and he said that was in good working order... Nice clean break at 3#... I haven't looked into anything yet and was just looking for ideas, recommendations, people, places, things you'd do to build off this action? It's the trap door model from 1986, made in Japan... Can it be converted to a detachable mag?

If you like the rifle itself and want to keep it and just want it to shoot better, the most economical solution is to rebore the barrel to another caliber. You could make it a 300 wtby or a 340 wtby, after reboring you have new rifling.

I had them rebore a 300 wtby to a 340 wtby:  http://www.35caliber.com/index.html

That's another great idea... My uncle bought a 300 Mark V Weatherby in 83', my dad bought the 7mm Mark V Weatherby in 86'... They were always shooting and arguing which is better and why, blah, blah... Funny to think that my uncle may still may win this argument after all... LOL     I shot them both side by side in my early teens, the 7mm was intense then, pretty manageable now... The 300 wholloped me... Recently the only 300 I've shot is a Winchester mag and they don't compare to 300 Weatherby... I'm not a huge fan of recoil... But shooting a belted mag I guess that's part of the course... My .50 Hawken is the worst recoiling I've dealt with...

If you shoot 150 gr Barnes bullets in a .300 wtby it shoots like a lazer and will go completely thru any animal out to 500 yards because Barnes bullets do not lose weight on impact. The recoil is much less than 180's or heavier bullets. I also shoot light 165 Barnes in the 340 wtby and recoil is like shooting a 30:06, but at 400-500 yards the bullets go thru an elk.

I like the sounds of that... I was raised a 7mm snob...

I have a couple of thought's to add
1) all of my factory Weatherby have a pressure bandabout 2" from end of stock applying slight upward pressure.  friends who have removed this have suffered accuracy issues.
2) Glass bedding an action is easy to do and corrects a myriad of accuracy issues.
3) All of my Weatherbys shoot good for three shots  and then it gets wild as the barrel heats up
4) Check out Oregunsmithingllc.com for there line of composite stocks.  I have no personal experience but am giving them a hard look for a future build .

Now I am going to try Bearpaws recipe for the 340 and see what I can come up with. 

Good luck whatever way you go.

Thank you I will check them out... And I noticed the same thing when she was a tack driver... I could get a great 3 shot group but they'd climb to the right every shot after... I never knew anything about the pressure band... I don't see anything visible...

I have a couple Mark V takeoff barrels, they might spin on and headspace and you'd be good to go.  I'm close to you, let me know if you're interested.

Might be cutting it close opening .284 to .308.  Prolly clean up though.  I'd consult with Jessie before getting serious though.

Certainly the cheapest option other than perhaps a takeoff barrel.

Relieving some wood that's touching isn't rocket science.

He did nice work opening my .264 to .338.  Big step, but did leave 1/8" at the muzzle.

The more I think about it the more I want to keep it 7mm Weatherby... So the take off barrel is probably my best option...
