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.
