Is it true that biodegratable airsoft bbs dont work with automatic guns?

Question

I bought an pulse M70 its electric and automatic and i shot off a bunch of plastic bbs wit it and it worked fine but when i tried to shoot biodegratable bbs it shot like c**p like it would shoot like 2 bbs at once and theyed only go 10ft

Answer 1

i wouldn't really call a mini mp5 gun a good gun to fire .2 gram bb's

first off no offense but that gun is kinda crappy. but yes all  other guns can shoot .2 bio bb's caus my Ca m4 can, and all my pals guns can mini guns might have trouble cause the bb weighs too much. and they dont make .12 bio's id save up to get a better gun to shoot those cause it's too heavy for the spring dude.

Answer 2

I think becuase your gun is gravity fed bbs and mabe its damaging the bbs. I have the Crossman stinger P9 and the bio bbs might work for my gun and can you tell me where did you buy your biodegrable bbs?

i can't find it at walmart or Di cks sporting goods

Answer 3

Did you try shooting regular BBs again? If not, try that and if it still doesn't work, it's because it's a Crosman. I had a pulse r74 and it only shot every other round, unless you held it upside down. Then the winding mechanism to load the clip broke, so I took it back.
