These BBs are the BEST bio bbs you can get. I have used almost al of them and I haven't got one jam or any other problem. The only thing is, at least in New Mexico, these take a long time to biodegrade. It's really dry here, so I expect in a wetter climate, it would go faster.
Also, I should note that they split in half on impact once in a while.
BUY THESE BBS!!!!!
-no jams what so ever
-Takes longer to biodegrade than expected where I live.
