Building a 340

[Bigbear]

I am thinking of building a 340 wby on a sako 85. I have a 300 win and a 375 H&H. I want to just have 1. The 340 is the best in between caliber I can think of. I have all the fast cals and small calibers covered. Looking for some input.
Thanks.

The best and least expensive way is to buy a rifle in 338 WM and just have it rechambered. I just did this with a new Win Supergrade and ended up with a beautiful rifle that shoots excellent. Also no bluing or other messing around, knock the barrel off and in 1/2 hr you have a 340 Wby. I've had 340s for many years and it is an amazing cartridge, I really recommend a 26" tube though, to realize the full potential. This was why the Supergrade caught my eye, available in 338 AND a 26" tube. I make all my brass out of readily available R-P 375 H&H brass, works 100% @ 1/4 the cost of Wby brass.........used to use W-W when it was available. Just got Marshal @ Matrix bullets to make me some 240 gn boattail bullets for it to try out, I think this should be the optimum weight for the 340 and have loads made up to range test tomorrow.
Make sure the action is long enough, I'm not familiar with the new Sako models but if it's made in 375 it has to be long enough, you may have to knock out a magazine block or replace the follower not sure on that action. Is your bolt throw and magazine the same on your 300 and 375, if so, you should be fine.

The .340 Wby is a super cartridge, but it's a kicker. The stock may need reinforced to control splitting. Pick a stock design that helps with felt recoil and select a scope with proper eye relief. Some of the new crop of recoil pads will help tremendously.

I built mine on a 700 with a RKS gain twist. 26"bbl. Lightweight synthetic stock. 1.5-6 B&L scope. Easy to carry and a hammer on game. Also a hammer on your shoulder, but that's the price you pay. - dan

And a great game getter cartridge . Probably the best all around NA cartridge for hunting everything on the continent from deer to polar bears. - dan

Actually Dan, it gets my vote as a world wide do-all cartridge, right up there with the 375 H&H. It is a better choice on the sheep mountains with a 180 or 200 gn bullet, and gives up nothing with a 300 gn solid to the H&H. And everything in between with a 250 Part............

Yup, pretty hard to beat the 340 Weatherby. Mine is make up on a push-feed 300 H&H M70 donor with a Smith S.S. barrel, Mag-na-ported, synthetic stock, and 1.5-6X Schmidt & Bender. It likes 225 TSX over a max charge of RL22 for just shy of 3100. It hits like a freight train.

opps, geezzzz! When I saw building a 340, I assumed 340 Mopar! I know it's a gun site, I just didn't think of 340 Wby! Sorry! I had tons of info, but forget it, I know nothing about the 340 Wby!
