These bbs are absolutely awesome. I was hitting a 3 by 12 street sign at 175 feet [measured]. Absolutely great in my g98. Much better bbs than my javelin 0.40g and my madbull 0.40g.
Pros:
accuracy
range
dropped my guns fps to about 410
Cons:
PRICE$$$$

These BB's are absolutely amazing. I've used a variety of different BB brands (TSD, Javelin, G&G) before these & I will say that these are the most precisely constructed & most accurate BB's I've used to date. These things are so round & smooth that that they can be a little slick in the hands & they fly out of the barrels with no resistance.I have had jams with some of the other brands, not a single one with these puppies. Some may say the price tag is a bit steep, I can somewhat agree, but one must keep in mind that Biodegradable BB's have always costed more than their standard polymer counterparts. I have every intention to make this brand the standard issue BB for my squad.
Pros:
Biodegradable
Great accuracy
Flawlessly smooth
Cons:
Cons?
Other than maybe the price, I have none to report.
Try a bag & see if you have the same luck that I have had with them.

I hate to be the bearer of bad news, but these BBs are worthless. I ordered a bag of these for a 545 FPS M16 sniper.
I have over 25 guns from Lancer, A&K JG, G&G TM VFC, and KWA. These BBs wont feed in any of them. I also ordered 3 bags of .25 same thing. I ordered these because of the good reviews and the fact that I need bio BBs for a op coming up. I use .43 of another brand and can hit a 5.5x5.5 target at 75 yards. I was lucky if I could hit a man size target at 75 FEET. My son in law ordered the same thing. He had the same thing happen to him. All he owns is KWA. I cant with a clear conscience recommend these BBs to any one.
Pros:
The BBs look really good nice and slick.
Cons:
BBs wont feed no matter what mag is used.
