Cheap practice in a rifle that is exactly the same as the 308 you already own. Same trigger, bolt throw, scope, etc.
Even at $400 more than a Norc, that's less than a case of surplus 308. At $200 per 1400 of 7.62x39, you can still shoot a lot more for less if you burn 1000s of rounds of practice per year.
Though personally, I'd like to see Savage release a Scout in 22.
