okay i have an unmodded 1077, so what would be best for hunting birds and small animals?

Depends on how good or bad a shot you are.

12gm caplets in a stock 1077 are good for about 30 consistent shots at 70*F, airsource tank about 300 shots. If it takes you 300 shots to kill a few birds- you should probably find another hobby?
