Is there anything between an a .12 gram and .20 gram airsoft bullet?

Question

my gun has 300 fps and if i use the .12 gram ammo, it curves really bad. if i use the .20 gram ammo, it sinks and doesn't go very far.

Answer 1

Your gun is low powered and rubbish. Get a better gun.

Answer 2

are you sure your gun is 300 fps. try shooting at a coke can from 3in away and see if it can go through. if it cant then its not 300 fps. if it doesn't then you need a better gun. what type do you have? brand? make ak47, m4, mp5, or some sort of sniper?
