Well, now I'm downright confused. Because I get a magazine with 10 rounds to use for reload! O_O I don't think I'll figure out exactly how everything interacts before the Banner is done. Well, I have both a Field Scout and Perfect Balance build in there so it's OK. xD I'm pretty sure with Heavy Ammo+ you get 26 + 26 rounds, so 50 + 25 rounds isn't that drastic a difference. 52 is enough to easily get a 10-kill streak up to a 15-kill streak if you're efficient with your ammo, so both builds are useful.
