By far my favorite across the board cartridge. With the .375 H&H following it up as a close second for hunting A-Z.
9.3x62You can get it rebored in Oregonhttp://35caliber.com/8.html $225 for 3 groove $250 for 4 or 5 groove includes return shipping on std rebore jobsIt is a real whomper
.308 NormaThis will give you an excuse to say "Norma" all week at hunting camp.
But you already have a 338WM. So the 338-06/35Whelen/9.3x62 selections are going to mostly duplicate it, granted with significantly less recoil. So maybe something smaller as JDHasty suggests.
Having just gone through this, it depends on how much you want to spend. For 30-06 the 338-06 and 35 Whelen are the easiest as they just use the same brass and chamber sizes. Simple re-bore the barrel to accept the larger bullets, and double check head spacing. If you reload, go for the Ackley Improved versions for the extra handful of grains of powder. JES reboring out of Oregon does the best work, JDHasty already posted the link previously in this thread. Next up is 9.3x62mm. Basically a metric "whelen", slightly better ballistics with .006" larger bullet (and a few more grains of powder) Very popular internationally, and some countries in Africa grandfathered it into their caliber restrictions since it was designed there specifically for that region (well, by a German, but for the African colonies). A bit more gunsmith work but still do-able. But the gunsmith will want to verify your barrel thickness to make sure you still have minimum barrel thickness to handle the rebore. Unless you re-barrel, then the sky is the limit (but costs double)If you re-barrel, and switch to something like a 300 win mag or other that causes bolt and chamber changes, you're going to easily creep up close to the price for just buying a new gun. Unless as JDHasty suggests you have a spare 300WM magnum bolt lying around. If I were going to go crazy with a mag changeover I'd go sexy with a 358 Norma mag. :-) My gunsmith wasn't comfortable going 9.3x62 with my barrel, so ended up choosing the 35 Whelen as I wanted larger frontal area and ability to shoot bigger bullets without having to step up to 338WM/375H&H recoil. It was designed by Americans as a poor mans 375 H&H before the Brits released that design to the US. A 250gr bullet at 200 yards is only 160 ft-lbs less retained energy from a 35 Whelen than a 338WM, but uses ~25% less powder to get there. Due to the higher BC the 338WM is significantly better once you get past 400 yards though.But you already have a 338WM. So the 338-06/35Whelen/9.3x62 selections are going to mostly duplicate it, granted with significantly less recoil. So maybe something smaller as JDHasty suggests.

So maybe something smaller as JDHasty suggests.Having shot my buddy's .338WM side by side with my 9.3x62 I'd question the assertion the .338 is significantly higher recoil. Never having shot a .338-06 or .35 Whelen I can't speak to those cartridges' recoil, but my perception was that the 9.3 was harder recoiling than the .338WM. My 9.3 is a CZ, so it's no featherweight. I think the 2 rifles are similar in overall weight, including glass (the .338WM is a Rem 700, prob ADL, but far from positive). I'll grant that I was shooting 286gr handloads that are fairly warm in the 9.3, and my buddy's .338WM had 225gr factory Core-lock ammo. If I stepped down to 250gr in the 9.3 or he had heavier handloads for the .338WM I might have decided differently. But I still don't think the recoil would have been "significantly" different. Noticable, perhaps, at least in a side by side comparison, but not different enough to sway a choice.
The only real option is the 22 Satan (22-06 improved) everything else is just pointless. Use a 12" twist barrel and throw 40 grain bullets at around 4400 fps. Should make a great deer killer when they decide to allow 22s for big game in WA.

6.5-06
Achley Improved, Norma, Whelen, Satan.....with names like that my cool factor will absolutely go up! I am liking the idea of going down from the 270 in caliber. 257 AI is interesting. How does that compare with the "vanilla" 25-06 from a practicality standpoint? A speed goat/varmit gun would make a nice addition to the safe and then my 270 and 338 won't get their feelings hurt so much. Thanks everyone for the thoughts and ideas!

If so, my first pick would be something in a 6.5 caliber like a 6.5-284, 6.5-06, maybe even 6.5-06AI.As for any problems converting a standard bolt face to mag bolt face or even super mag bolt face, WTF are you talking about?! Standard bolt face Rem 700's get opened up to mag bolt face diameter alllllllllll the time. I've NEVER heard a gunsmith recommend against it. I even have a LA Rem 700 that's been opened up to the super mag 338 Lapua size bolt face. You'll obviously have a little more money invested in machine work because they have to open up the bolt face and then machine a slot to install a M16 or Sako style extractor but beyond the added cost, it's a none issue. But, since you already have a 338 Win mag that has a mag bolt face, it wouldn't make much sense to spend the money to open it up to a .540 bolt face.The 280 Ack Imp was mentioned earlier, not a bad choice either and would be an easy one to load for using Nosler 280 AI brass but since you already have a heavy hitter in the 338 Win mag. I'd probably go the other direction and look at something in a smaller caliber, maybe even think about a fast twist 6-284 to shoot the 105's but I'd most likely go something in 6.5.As for reboring a factory barrel, IMO, that's just, potentially, throwing good money after bad.

Negative. I believe factory barrels are marginal and good quality custom barrels just don't cost that much so I, personally, see no point in spending money on something that is marginal to start with and hoping it turns out well. I don't know any gunsmiths that'll give you any kind of accuracy guarantee if you chose to use your rebored factory barrel on a build.
In the grand scheme of things, a good snout is cheap... skip the "re-bore" and get a 6mm-06 or 6.5-06.

I have seen Remington pumps that were reborred from 30-06 and they shoot very close to an inch at a hundred yards
