That's why the old Soviet Union adopted it as standard in 1974.
There was an article in pdf format on the 'net somewhere - I'm on my ofc PC and do not have the link, but some military journal (Aussie author?) reported that the ex-Soviets were starting to re-think the 5.45x39 based on poor performance in Chechnya. They missed the knock-down of the heavier 7.62 bullet.
As I understand it, some ex-WARPACT satellite nations switched to .5.56/.223 (Poland, Romy?), several stayed with 7.62x39 (Czechs, Hung, Albania, Yugo??), and only a few stayed with 5.45 (Bulgaria??).
I'm sure others will fix this.
Regardless, thanks to the Mini-30 and the gazillions of CHICOM SKS that came in-country, the popularity of 7.62x39 is rock solid and can be found in various loadings at WalMart, Dicks, Dunhams, Gander Mtn - pretty much anywhere.
Not so easy for the 5.45x39. Once the cheap corrosive mil-surp 5.45 dries up in the market from the ammo-hoarders buying pallets at a time - the biggest attraction of your 5.45x39 rifle will be gone. Unless you are lucky enough to have the financial freedoms to be hoarding surplus 5.45x39 right now...
