My old Boomstick shot this paint very nicely. My Check-It Products JR-3 Series also shot it nicely, but if it were .687 it would've been better.
Never attempt to use it in the cold
I bought a bag of X-Ball Bronze to see what my two guns can really do, it was the best paint my shop sold in bags of 500. I must say, this has restored my faith in DXS paintballs. It shot very accurately in my PM5 and my Autococker. The PM5 was using a .689 barrel and I think my Cocker's barrel is .688. It fit better in the Cockers barrel, I think this paint is .687. It's very consistently sized and has no seam on it, at all. The fill on it is very nice too, I liked it. It was also brittle enough to always break.
My only gripe about it is that the shell is very brittle in the cold. I was breaking a lot of paint in my loader, which brought it down to my feedneck, eyes, breech, which caused barrel breaks, which enough of this crap lead to chops even. Overall, it took me 45 minutes to clean my PM5's breech, the barrel for my PM5 and my Cocker, and take apart my Reloader B because of that. Not a good thing at all. I don't expect this problem in the summer though.
This is a friggen' good paintball! My faith in DXS products has been restored. I'm going to buy this as much as possible, maybe convince my local field to start selling it instead of selling Rec-Sport only.
