Plus, watch barrel lengths. Norma uses a long barrel. But that isn't unique.
That was taken into account, circa 1983; Cooper initially wanted [email protected], then decided he wanted an impact velocity of 1000, so the load was bumped a little; the designers wanted to ensure the rounds would make the published velocity in a 5" barrel, so the load was bumped a little more, in case Norma was using a longer barrel, etc.

Similar to the ground trod by the .41 Magnum, twenty years earlier, in that it was supposed to be a service cartridge, but as long as there was also a "magnum" version, all guns had to accommodate the hotter round, so, no mid-sized .41 service revolvers.
