What about the .338-06 Ackley Improved? I've been thinking about this one for at least 10 years. Should make for an ideal Moose rifle.
Nothing like gaining a whopping 25-40fps and having to fireform brass.
Not a cartridge that benefits much.

Winchester is one of the worst companies for chambering variety. You're probably better off barking up Ruger's tree.
Go, talk to Winchester, see how far you get. Let us know please.
No need, I have a .338WM...![]()

And it is such a chore to fireform brass!
The fun of wildcats is getting to tinker and shoot something that is not found on the rack of every gun shop on the continent. Otherwise we'd all be toting .30-06 Winchesters and shooting 180gr Power Points.![]()
The 338-06 , like the 35 Whelen which is equally as good, lacks the magic words "magnum" or "improved" in it's title. The 338-06 make no impressive velocity claims or has magazine writers making glowing testimonials about it so there is little interest in marketing it by the major makers.
Most of us who do use it however are very happy with our choice and appreciate the performance a heavy bullet at moderate velocities delivers.
always wanted a 338-06, it struck me as a near ideal choice for bigger game in BC like moose, elk, grizz and big black bear. Took me about 15 years but I've finally got one built, should have it soon
Like you said, great caliber choice for your listed animals. I made mine in the AI version (to be different) but love it with 225gr AB's and TTSX's."Would you wear a watermelon on your head and march in a parade just to be different?"
Well yeah, actually I might. - dan
The short answer to the OPs question is there is just no justifiable need for this cartridge. It's ballistics are duplicated and improved upon by so many other cartridges that the is no reason for this cartridge to exist. It certainly won't do one thing more than the 35 Whelen or 350 RM it's just a tad better than the 338 Federal, 358 Win, 8X57 and doesn't hold a candle to the 325 WSM, 338 WM, 358 NM, 9.3X62 and on up.
Another factor which hasn't been addressed is that the 338 bore is barely hanging on in sales of all the commercial cartridges available now. It has a fan club for sure, but it is a small club in the big picture of rifle cartridges available. This fan club is also almost totally made up of the big 33s from the 338WM on up to the 338X50 BMG for looooong range shooting.
The Federal is the latest 33 to hit the market and it may survive (but I doubt it) solely because it is based on the 308 case and short action.
My question back to you OP, why SHOULD the 338-06 be more popular?
I've been reading a little about this cartridge. It seems like it's a pretty good idea to me and I'm wondering why it isn't more popular ie)why are rifles not offered by manufacturers in this chambering? It looks like most guys have custom builds. I'm assuming that because there are not a lot of rifles around that factory ammunition is limited. Any thoughts?
