Using the dimensions of a .375 Ruger (2.275" to the neck/shoulder junction) and a 225AB I get 3.59" OAL. It would be a little bit longer then that because as you neck a case down the length to the neck/shoulder junction gets longer. It's not that much work to install a Wyatt box so I'd do it to maximize the potential of the case especially if I planned on 250's.

You could probably use the magnum or H&H follower and have it feed fine. A standard magnum case is .513 without the belt (.532 with the belt) and the Ruger is .532. A RUM is .550. If anything it would take very minor feed rail or follower modifications to make it feed right.
That is kinda what I was thinking. I would almost bet it would be okay with the standard mag box, but I want a little extra length, I think. I do like the looks of it with the 250's and at around 2900, that is just about exactly what I am looking for outta this rifle.
I'm also interested in building one of these. Which of my donor rifle options would you recommend? I have a stainless Ruger No. 1 and a left handed ss/lam Hawkeye 30-06. Is there enough metal in either barrel to simply rebore /rechamber or should I just rebarrel altogether?
I think the Hawkeye done with a 22" barrel would make for a hell of a gun. Carries like a regular ol hunting rifle hits like a high power Magnum. No interest in the 338RCM, I just don't see that being around for a long time, and I might as well go with the 338-375 if I gotta reload anyway.

Well sorry, it ain't a 340Wby and just the cost of doing a wildcat having a consistent shooter that has consistent accuracy and velocities in a purer hunting rifle for the field when one can purchase a 340Wby that a handloader can actually drive faster than Weatherby factory ammo, I know I have done it and this with a Mark V action and 26" barrel, not some 29" plus barrel. When you consider the Weather Mark V chambered in 340Wby I have no need whatsoever of having to build a 338/375 Ruger. Will be interesting when Ruger if they do chamber their rifle in 338/375 Ruger what the real numbers will be, because the Ruger is not near as strong as the Mark V. I know one guy who has built a 338/375 Ruger that is getting 340wby velocities but it is a 29" barrel and certainly not a rifle for the field.

I love the belt, and love the double radius shoulder, so what is you point? You don't assume the belt was put on belted magnums for strength did you and you have some info that the double radius is flawed and both the belt and double radius cause the cartridge to not be accurate? Once again what is your point?

The double radius shoulder is a GOOD thing in any cartridge ! :grin: RJ

I mean that case capacity is very close and from what I have been able to deduce from QL, they should be very close in velocity as well. I'll have first hand knowedge to share hopefully before Christmas.
Reinventing the wheel, yeah maybe. Having a blast builing it exactly how I want, absolutely!

This is just me and I like the 340 a lot, but I was going to do the 338/375 build just because I liked the 340 so much and wanted to have the ballistics of a 340 in a standard length M70 action. I don't mind the belt nor the radiaused shoulder. But not having to deal with them was okay my me as well. They are identical in case capacity and if you use a 3.6" mag box for the 338/375 you can seat the 250's out quite away. Really lets it run.
My wife got me a M70 Alaskan so it squashed my plans of doing the 338/375 as I like the Winchester as is, and again, the belt doesn't bother me and with a 25" barrel, my 338 will get everything done i want done. Just my thoughts on the project.

My point is that there are differences between the 340 Wtby and the 338/375 Ruger. So since this topic was about the 338/375 Ruger, why talk about the 340 Wtby. We are all aware that there are different calibers that have similar performance, so if we were discussing a 280AI do we have to discuss 7 mags? Why/
Sure everyone loves their own guns and choices but you shouldn't steer the conversation back to your own just because you love the belt and radiused shoulder
If you can have reasons to like the 340 Wtby more than someone else's choice why do you belittle my reasons for liking the other?
And I can come up with reasons why the Wtby (belt and freebore) is not optimal but choose to let you have your own reasons for loving it without question

These threads do wander and get off topic, no need to get too upset by it. It has all been friendly so far. Just a comment about the .340 Weatherby: I was getting 2890 fps @15 feet velocity chrono'ed from the 250 Partition from my Mark V Weatherby. Certainly a velocity mark to be noted as it is slightly over 2900 fps actual.

If the .338-.375 Ruger can get into that velocity range, it will still be carrying over 2200 foot pounds at 500 yards. That is a reach-out-and-touch-them load! Patrick used my old .340 Weatherby to kill a nice bull elk at over 500 yards with the 250 Partition a couple of weeks ago.

Yes, a 340Wby no trouble, Weatherby factory ammo moves it at 2941fps out of my 340wby and using 250gr Sierra with 7828 and RL-25 I got 3032 and 3041fps and this is with a 26" barrel. I even got my 8mm Rem Mag to 2812fps with a 250gr barnes original. Drove a 240gr Northfork in my 340Wby at 3066fps.

That is GREAT to hear Charlie.. I loved your old 340 buddy. If I had been gifted the rifle I have always wanted just before that, I would have been all over your 340. I am very glad your 340 was able to get into the elk this Fall.
Your right though, 250's at anything over 2900 is carrying the mail!
