Monsterdog I did think about the 300 black out and 458 socom and 7.62x40WT but ammo availability and cost have narrowed it down to 7.62x39 or 5.45x39. It's a hard decision. lol
edit to add yeah the old mags had issues but there are some reliable options now.
300 AAC BA is a reloader's dream, or so I heard. Basically a 308 cartridge in a necked down 5.56x45 casing. So if you reload this ammo should be fairly cheap and plentiful
