Avenger minigun spews very very many 60 damage bullets
Kord (sniper-machinegun) is a really powerfull (1 hit KO) sniper with some burst fire. I reccomend both :)
Tips: when the big zombies get too near to you then stop shooting at it and it will find somthing else to pwnzor.
Also: dont spend money on anything unless you are out of shotgun or grenades If you need full health then wait for a pack and hope thos little invissible zombies or the one thats rly fast get to you.
