Here's a few things to consider about Corey's idea.
First of all, as posted earlier, the 35-300 Savage has been done before. There really is nothing new under the sun. Not sure who posted it here first, but I like the suggested name, 35 Cowboy. All in favour say, "AYE!"
Next, factory 35 Remington ammunition gets around 2000 fps from Marlin rifles with 20" barrels. Directly from their website, SAAMI shows the agreed performance level for factory 200 gr to be from 2050 fps-2200 fps at from 35,000 to 37,200 CUP. This is the standard for factory loading of this cartridge.
Now, the SAAMI pressure standard for the factory loading of the 300 Savage is 46,000-48,900 CUP. This is not only 10,000-12,000 CUP higher than the 35 Rem, but in a case that has only slightly less capacity, about 4 grains, than the 308 Winchester.
This is why the factory 300 Savage 150 gr load was able to duplicate the original 30-06 military load of close to 2700 fps. Neat!
Consequently, the 35 Cowboy is able to be safely loaded in stronger brass, that is of greater case capacity, and to higher pressure safely. The end result, as we all understand, will be somewhat higher velocities, certainly far above factory 35 Rem.
As well, Corey's Cowboy will most likely have a 22 or perhaps a 24 inch barrel, getting even higher velocities than the 35 Rem in a 20 inch barrel.
The fly in all this ointment, of course, is that reasonable men would just rebore a 308 to 358 for several obvious reasons,.......... but then, that would be boring.
