The 7 RM is the cartridge that knocked the 264's nose in the dirt and relegated it to relative obscurity.....where it remains today, except maybe on Internet sites
I agree with what Ken Water's wrote in Handloader about the 264 being a fine cartridge, but where Winchester erred was not making it a 7mm. And judging by what happened when Remington released the 7mm RM a few years later, he was right. Not including military rounds, it's got to be (or at least one of) the most popular cartridges released in the last 50 years.
Wasn't so much the headstamp or the chosen projectile diameter Remington fielded as it was Winchester's chosen projectile weights and Model 70 barrel lengths that "screwed the pooch" for the .264WM's future.
Regarding the .338Fed, I'd just as soon stick with the .308W. For multiple reasons.
