5.45 is the worst choice.
It isn't common at all.
Domestically there is no production. We're dependant on imports.
Internationally it is extremely scarce. The only country using 5.45 is Russia.
Even most of the former Warsaw pact countries are using 5.56 weapons and joining Nato. All of the major Eastern countries use 5.56.
China uses a proprietary cartridge, with 7.62x39 being the secondary. And they don't pass out their good guns like the Russians did during the Cold War.
African and South American countries that were supplied guns by the Soviets were given 7.62x39 guns. The 74 was never passed out like the 47.
So basically, for all over the world use, you're gonna find 7.62x39, 5.56, and even .308 before you find 5.45.
