Errrr......The Icebreaker ammo weapon swap thingy works way too well. I feel dirty.

edit2: Icebreaker with 6 ammo gives 17 shotgun, 18 sniper.
Dreg's promise and no armor perks gives 8 shotgun, 5 sniper, however Dreg's promise only works on *respawn*, you don't get ammo at the beginning of the very first round.
