RE: top 10 selling rifle cartridges?
7.62 x39 is a pretty common ammo for plinking, with SKSs being cheap, good, and widely available, it wouldn't suprise me if it were in the top 10.
I doubt it would register on the radar as top 10 ammo sold by manufacturers as alot of people buy it in bulk as surplus ammo from other countries. I would imagine in that case, 7.62x54r and 8x57 wouldn't be all that far behind in ammo consumption when you consider that alot of this ammo can be had for less than $0.10 per round.
