From Remington’s perspective I can see the attraction of developing this cartridge for niche US markets that have 1.8” straight wall case limits.
Use a shortened 30/30 case and bullets from a 35 Rem to produce ballistics that exceed those of (low pressure) factory 35 Rem. It might just make the 35 Rem obsolete.
There are a LOT of 35 Remingtons out there, there just needs to be ammo again. Once again, northern states are screwing the rest of the nation.
