Justify??!!?? You absolutely NEED multiple rifles chambered in cartridges that fit between those 2!!!
Then it boils down to want vs need! Lol. I want to do an AR10 platform first!

I would go 300 Norma mag you already have a magnum bolt face if you had a 30-.378 wetherby 300 Norma mag you get lapua brassI was hoping JE you would chime in . I love getting your wealth of knowledge. If I go 338 it'll be the 338-378 just because I've always and I mean always wanted one. Don't really know why just always have same as my 7 mm stw . I remember reading the prelude to its reloading pages in the nosler load manual when I was a teenager and after that I always wanted one . Finally got it .
The rum series of cartridges is something that I've always been interested into also. And I'm really thinking that I may end up going that route.
My buddy has the Lapua and I do all his loading . I don't mind sharing components just not brass. When I get around to rebarelling the current 30-378 I'm certain it'll come out 338-378 just because I've always wanted one . Long before I ever heard tell of the 338 Lapua magnum . I'll be perfectly honest about it though I've loved this 30-378 very much so it shoots better than I personally can . my buddy shoots it almost every time we go out better than I can. Ouch that kinda hurts to say . Lol . And he's always been a little better shot than I am . Don't tell him though .Lol....I did the same....but I have 3 sons..I bought them all the Vanguard's...me the Mark V! Why not go .338 lapua then!
I have two different reamers that I have used since before the 30-378 was offered as a factory chambering. Both of these reamers have no freebore. One is reamer is for small bullets and other is for heavier bullets. I have barrels with 14" twist and have shot 125's and 130's at 4000+ fps. This is a 26 lb gun and it has shot many 5 shot one ragged hole groups. I also qent to a 338-378 with a 2" BAT and 2" barrel in a 1000 yd heavy stock. This chamber also no free bore. 56 lbs and shoots 300 grain 2900 fps. Also chambered a 338LM IMP and it shoots 250 grains 3200 fps. I chambered a 338 RUM for my son and he shoots 180 accubonds at 3760 fps. It seems to be the most exciting of all of these and produces the most explosive results. My 338-378 did not seem impressive at 752 yds. Perfect lung hit and deer ran 50-60 yards with an exit hole little bigger than a quarter. That 180 accubond has a good advantage with its velocity and since we dont have many shots past 800 yards-the BC means very little if any at all. Only problem is brass. Not very good and hard to get. I am now chambering a barrel in 338 Lapua Imp to shoot the 180 accubonds. If I can get 3700 fps with 32" barrel and with Lapua brass I will be happy. Also chambered 300 RUM but like the 30-378 it is finicky having to small of hole for all that powder charge. Overbore can be a problem. I would like to go to 375RUM as it is the most efficient and probably the most inherently accurate RUM, but cant get Lapua brassSo my 30-378 maybe on its last hundred rounds. Last 2 times out it's showing signs of needing rebarreled . It's on round count 1450 ish been a good shooter and very happy with its performance. With that being said I've been looking into the 300 rum quite a bit . In all reality from what I've read there really isn't that much difference between the 2. But I like to tinker with new guns/ chamberings . Granted I'm all set up for the 30-378 as far as reloading stuff but another set of dies really isn't that much. And I may have the weatherby made into something a little bigger in the long run anyhow. 338-378 sounds FUN!
With what I've got now I generally only punch paper out to 1000 and am comfortable shooting game in the right circumstances out to 700 yards. Which path to take . Should I go back with the 30-378 or Jump on the rum bandwagon
You have my word.....but sounds to me like you could order a Krieger barrel direct from Weatherby and stay with what you love.My buddy has the Lapua and I do all his loading .

Stay with your 30-378... love mine. Got about 900 down the pipe.. when it's toast gonna just re-barrel just not sure who's Barrel I'm gonna get.. Have a custom 338 RUM as well... the 338-378 also has caught my eye for a future project... good luck on whatever you choose!So my 30-378 maybe on its last hundred rounds.

Try a Lazzeroni Warbird it outperforms both. If not that I'd go to 30-378So my 30-378 maybe on its last hundred rounds. Last 2 times out it's showing signs of needing rebarreled .
