I was using my boomie which seemed wayyyy to big for them. They dropped strait through right past the nubbin. It still shot okay.
Fairly consistent, super thick fill.
The seems, if you run your finger across the ball you can feel them.
Even though they where way small for my boomie I was still getting good shot groupings at all distances. Because they where small they where causeing my velocity to fluctuate but that is my fault. I did have one break, it wan't a chop and it wan't a barrel break. I really don't know what happened but it was enough to take me out of the game. 1 out of 20 of them are sized way bigger then the rest. The seems don't look good but it don't seem to effect shots to much.
I like them, if I had a barrel that they fit I would use them all the time. They are cheaper then marbs and with a good paint/barrel match would probly shoot nearly as well. Most of the problems I have with them is they didn't exactly match my barrel so hot.
