I didn't realize that there was any CHEAP 7.62 left.
Actually, didn't realize there was any 7.62 left, CHEAP or otherwise.
As for which caliber to get, I struggled with that decision recently myself. I picked up a Saiga and ended up getting it in .223 vs. x39. If the supply of foreign x39 dries up (because of a ban or heavy taxes), I thought a US caliber might be easier to acquire....and worse case, I can reload for it from the supply of brass I already have. If my assumption is proved wrong and 7.62x39 continues to be plentiful at a reasonable price, I'll buy another Saiga in that caliber.....oh darn the bad luck.
