338-06. The poor man's 338 mag. Very effective.
Of course you must reload to get the benefits of the cartridge, or you'll be stuck with the Whelen

The 9.3x62 will drive a 286 grain bullet about a 100 fps faster then the 338-06 can drive a 250,that's about 500 more pounds of bullet energyJohn Y Cannuck said:338-06. The poor man's 338 mag. Very effective.

Right, and with five in the magazine!

From my Barnes manual, max speed listed with 24" barrels:
.338-06: 250gr @ 2448fps
.35 Whelen: 250gr @ 2586fps
9.3X62: 250gr @ 2644fps
Not a whole lot of difference if you ask me. So far I'm leaning heavily on the .35 Whelen. 286 @ 2700fps?? I don't have any experience with that caliber buy Barnes lists it's fastest load at 2500fps for the 286gr 9.3.

35 Whelen and 338-06 are both deadly to Moose and Elk to 400yds with decent shooting and, if you are a better shot than me, a bit further.
I have a couple of 338-06 rifles that shoot well and not been used as much as my 35 Whelen rifles for no particular reason.
Both calibers hit hard and accurate with good loads and recoil is reasonable.
Brass, bullets and powder are easy to find.
The only change to a 30-06 rifle is a barrel change or a rebore. The boltface remains the same and both the 35 Whelen and the 338-06 will feed properly from a 30-06 magazine.
Works for me.
Good Luck

Cartridges of the World gie a 286 grn bullet at 2500fps, a 286 Norma load at 2360 and a RWS load at 2430 for a 296 grn bullet.bcsteve said:
The 9.3 X 64 Brenneke is better, with a 285 listed at 2690 and a 293 at 2570!
The rim is larger on the Brenneke at .492 against .470!
Okay, resisted long enough...
I had three Rem 700's in .30-06 at one time. Yeah, I know long story....
Right now I still have all three Rem 700's.... One's still a .30-06 [thanks, Doug ] and the other two have changed somewhat... one's a 24" barrel .270 and the other is a 22" barrel 7mm-08...
Yeah, I'm happy with it...

I get 2600 using a 250 gr over W760 in a 24" barreled 338-06. The load matches exactly what is in the Hornady manual. In the Speer #13 manual the write up on the 338-06 mentioned that bullet weight for bullet weight their test folks noticed the 338-06 would beat the Whelen by 100 fps in most loadings.
I'm not a ballistician but isn't their a rule that says that pushed from the same case, a same weight larger diameter bullet will have higher velocity because of the increased surface for pressure to push. ie: a 150gr bullet would have higher velocity out of a .308 Win than a 7-08 or in this case a 250 gr out of a 35 Whelen than a 338-06.?

To a certain point that is correct. With the 30-06 family of cases it seems the 338 bore is optimal when it comes to chamber pressures and expansion ratios. At least Speer and Hornady found that to be case with their data.
In any case it is all "paper ballistics" as in the real world no animal will ever be able to tell the difference between any of the 3 rounds suggested so far.
.
I think the main reason 338-06 gets higher velocity is due to it being loaded to higher pressure. Could be wrong but it just makes since that a larger bore diameter has less surface area for the same weight bullets. The .35 whelen was created when alot of older rifle were still in use and being converted.

Bingo!!!!!!!
For the .35 Whelen the Speer manual lists a max load of 54 gr with RL15 for about 2400fps with their 250 gr bullet. That about 5 gr less than other manuals and would be a suitable load for older rifles of questionable strength or chamber dimensions..
Loaded to the same pressures, the Whelen will perform as well or, probably better, than the .338-06.
In my Whelen with a 23" barrel and 250 gr bullets I'm getting 2600 fps with less than max loads and with the 225's I'm getting 2725 fps, again with less than max loads.
I'd go 338-06. Just because I have nothing between 30-06 and 45/70.
35 Whelen would also be good, but for some reason, I'm getting the 338 itch myself. I might even look into 338-08, or 338 Federal as it's recently been named.
That's just me though
