And your neighbor in Rathrum invented and named it about 20 years ago - still good!
mountainman:
Take your existing rifle, screw a quality barrel in .338 Edge. Add quality scope and trigger, grab some dies and some .300 Ultra brass, add some H1000 and 300 GR. Matchkings or Bergers, and shoot👍
Jonathan_S:
H1000 does great in the Terminator too. N570 really shined and provided that excessive HP I was looking for.

Thought I might have a lead for you on a gunsmith who would work on a weatherby markV action. Contacted him and he said that he did not work on them as the cost of tooling needed to work on them did not justify the demand.

Part of the problem with using MkV actions, particularly with long high BC .338 bullets, is if you want to use it as a repeater you're very limited on the max allowable cartridge length. It's been awhile since I had my 338-378 but if I recall around 3.750 was all you could get in their magazine and I'm not sure there's anyone that offers an extended mag box for them like they do the Rem700 or 700 clones. It's not like that big Weatherby case is lacking capacity but the, only, reason I'd ever build a 338-378 would be because it has the biggest case of any production .338 cartridge out there so I certainly wouldn't de-nut it by limiting the OAL to 3.750
The 338-378 is a big long case and you stuff a long 300gr bullet in there seated to 3.750 it kind of neuters the capacity of that big ole 378 case. Not that you need to run one of these things as a repeater especially if you're using it for LR or ELR work but I wouldn't spend any money on a repeater type action to have to use it as a single shot.
My Wby Accumark 338-378 shot decent-ish but only if it was throttled back which made it kind of a turd in the velocity department. As soon as I got much past about a mid level load with the variety of different powders I tried it would start scattering shots all over the paper.
