Swap that .308 for a 6.5 CM and you won't have to dial much anymore compared to a 300 WM. About 0.5 MOA difference in wind drift at 1000

I think you know better than that; something about diminishing returns comes to mind.

I think its safe to say that the number of game animals taken beyond 300 yards with a traditional .30/30 lever action carbine would be pretty small, which is why its viewed as a niche cartridge rather than a general purpose big game cartridge. The .270 is certainly capable of such performance, and while a scoped M-54 Winchester in .30/30 might do it with a 125-150 gr spitzer bullet, it would certainly be pushing the envelope. If you're searching for a holy grail cartridge, consider one that produced today's modern ballistics 100 years ago, like the 6mm Lee Navy, the .30/06, the 9.3X62, and the .375 H&H.

OK; I'll bite. Which bullet and velocity on the Creedmore?
It would be one of the many great "do it all" two rifle collections.
I might even get a 65 CM one day, to match up with my 375 Ruger
Just used some factory ammo comparisons.
300 WM 190 SMK Gold Medal 2700 FPS
6.5 CM 140 SMK Gold Medal 2675 fps
1000 yard 10 mph crosswind correction
300 WM 7.5 MOA
6.5 CM 7.8 MOA
4% more wind drift with the 6.5, with much less powder and recoil.

That's why I don't use factory ammo, I can beat that .300 load with my .30/06. Add 300 fps to the .300, then how does the comparison shape up? I'm getting 2900+ with 210s in a 24" .300.
Yes, and we routinely load 180s well past 2800 fps with excellent accuracy, good case life, and tight primer pockets.

You can also bump the CM up 200-250 FPS and keep the same ratio of wind drift. I was just using factory ammo as it's easy to compare
I wouldn't be accepting that 2700 as any kind of gospel, when the GMM 190 load has been 2900-2950 since christ was a kid. Likewise with the Blackhills and Hornady. I can just about make that 2700 with my .308 and 210 VLD albeit with a long pipe. My handloads for the 190 SMK, 190 VLD and 190 ABLR are going at 3150 fps.
That will put the SMK at 6.6 MOA, the VLD at 6.1 and the 190 ABLR at 5.1 MOA.
I'll give you a better bullet though, say a 143 ELDX with a G1 of .625 at 2700. That's up there with the ABLR 190
That will come in at 6.7 MOA drift, 1476 fps and 692 foot ponds.
The .300 with 190 ABLRs is 5.1, 1812 fps and 1386 foot pounds. So 31% more drift to the Creedmore, 336 higher velocity to the .300 and energy that I'm just going to round off to double.
I'm not immune to the charms of a 6.5 though; my 6.5-300 Win is at 3.9 MOA.

Using those numbers you are still at only 1.6 MOA difference in wind, whereas you said have to double it for your .308. Pretty good trade off for much less powder and recoil.
