Just did some digging and both red-star and wolf source most of their 5.45 from both Russia and Ukraine for manufacturing. 7.62 is a bit different of a story where Wolf is almost 100% Russian and red-start is Bulgarian. Personally I just placed a large order of 5.45 to hold me over for several years. Given the state of world affairs and the talk about punishing Russia from both side's of the aisle in Washington for it's armed incursion I can see 5.45 drying up fairly quickly. Think about what happened for China 7.62 after we blocked arms imports from them...
