"I am an older person but new to airsoft. As an older person one concern i have about my newfound hobby is resale of land i own and having BB's laying all around is a sure way to create issues for resale in later years.
I will be rating all the BIOs as i use them.
Physical Characteristics: Made from PLA (polylactic acid) which is used in many biodegradable plastic things we use such as cups etc. Basically it's made from Corn Starch or sugar cane.
In warm climates this stuff can break down as quickly as 47 days according to the packaging. Up to 4 years in cold climate ares (4 C, 40 F)
They are super slick to the touch, and i can see no difference in appearance from plastic non bios. Tolerances are the same under Micrometer readings. Under magnification i see no surface defects. If i were to mix a bag of these bios with other white non bios i could not differentiate the 2 types or brands.
No issues that i don't have with regular BBs, Good flight, Only 1 jamming instance and that was immediately after using silicon oil to clean and lube my barrel. I now run dry patches after my silicon patch to ensure i dry up any excess and i have had no further jamming issues.
I'm getting 300 FPS with these .2 bios and getting 150 ft easily with tight grouping.
Some say that bios are trouble for the guns, but i am not finding that to be the case. Maybe 10 years ago, but these are great ammo. Better to use Bios and not upset the land owners in my opinion. The G&G brand are a 5 star, i will be buying more. Next to order, buy and rate will be the Goldenball brand."
