Besides the 1.8" length limitation bullet selection is much better not just handgun bullets but jacketed .358 rifle bullets suitable for a lever action.
I have both the 375 win and 38-55 in lever actions and the jacketed bullet selection sucks there's basically two companies making them the 200 gr Sierra and the 255gr Barnes and both are seldom available there is also the bullets from Les Vollmer which are probably easier to get, or buy or cast your own lead bullets.
And for people that don't reload I can't remember the last time I saw .375 win or 38-55 factory ammo in a store.
I'm hoping more ammo companies will make 360 ammo besides Remington or make more .35 cal bullets.
I don't think it will be anywhere near as popular as the 350L the rifles will be just two expensive, except for the single shots and not available in a bolt action or AR type rifle
