your looking at 4000~ rounds before you recoup the cost of a 7.62x39 upper given the .15$ difference in steel vs brass. your limiting yourself to about 200yds max with the x39 cartridge. there are better rounds than the x39 if your intention is something more than plinking. cheaper to just get a sks/ak if you realllly wanna shoot that round.
the 7.62x39 is a pointless bullet there are much better rounds in it's power range. the soviets designed it to be compatable with the same powders and bullets as the 7.62x54r as it is merely a neutered version. its inherent flaws is why i think they have been switching over to a round very similar to the 5.56.
