the 338-06 and 35 whelen both potentially provide a noticeable increase in penetration and impact damage on game over the 25-06-30-06 class of cartridges provided the correct bullets are used. if you use bullets of 225-250 grain weight these cartridges do have a noticable increase in effectiveness, if you use the lighter weight bullets much of the cartridges potential usefull advantage over a 270 win-30-06 is lost. if you build a rifle Id suggest a 338-06 for the simple reason that theres a better bullet selection in well constructed bullets,most 30 cal bullets over 200 grain weight are boat tail, thin jacket target designs or round nose designs, neither is ideall for semi-long range ELK hunting.( 10-350 yards)
the 225 grain and 250 grain 338 bullets can retain a greater amount of energy at semi-long ranges than most 220grain round nose HUNTING bullets fired from a 30-06 ,there are two 338-06 rifles in use in my group of ELK hunting buddies, both have several one shot kills, both rifles are accurate,and both rifles weigh less than the magnum rifles they replaced, yet both hunters feel that no loss in effectiveness has been made, now keep in mind most ELK are killed at under 350 yards from or hunting camp/group, but I think youll see a noticable increase in effectiveness PROVIDED you stay in the 225-250 grain bullet range to take max advantage of the cartridges best feature, a great deal of penetration and relaively low recoil and rifle weight compared to some of the similar magnum rifles.the main advantage I see in these two cartridges is that you can build a lighter weight rifle than the big magnums yet still retain a gain in on target power from the comon and cheap 30-06 basic case, and rifle action and not need to burn a great deal of powder to do it, or need expensive cases, or a magnum length action.

btw I hunt with a 340 mag and a 35 whelen, BOTH cartridges definatly have greater penetration than the 30-06 I used to hunt ELK with. the differance in on game performance between the 35 whelen and 338-06 is extremely small, but again theres a better selection of bullets with thicker jackets and a slight advantage in ballistic cof. in the 338 bullets
heres some 35 whelen stuff.

btw if your into a slightly more exotic cartridge dont forget
9.3x62 and 9.3 x 64 use 250 g or 286 g bullets.
