Whichever one you presently have works best!Would like an FAL and lots of 7.62, but have ARs and 5.56, so that's an easy decision for me. I've been talking to special forces type guys lately and they're telling me they're opting for heavy bullet 5.56 (77-grain) out of a heavy barrel AR over 7.62 because of the bullet-proof reliability of the AR system. There is still 5.56 around in places (you have to look really hard), and magazines aren't an issue...Michael B
Whatever caliber you have CLOSE AT IN YOUR HAND.
Fixed it!
