Let's get this out in the open first, false advertising by airsoftgi. These bb's are no different than any other bb in size as on the package itself it says 5.95mm not 5.98 as shown on airsoftgi.com.
Anyways, still fantastic bb's. I use them in my Tanaka which granted, has some outstanding hop-up, but these are quite accurate. I have yet to see a flaw in one. My rifle is shooting 350 fps with. 2's so it has significantly lower power with these. However with the strong hop-up of the Tanaka I have outstanding range. I can hit fairly consistantly human sized targets at 85 yards. And at 100 yards the gas is too inconsistent to say i'm hitting consistent but not to say I can't. The accuracy here amazes me and I will continue to buy these.
range (due to weight)
Color (almost black)
No biodegradable version of these.
