only used the one i have presently, its not the stock barrel but i dont know which one it is actually.. illl find out later.. its 16" and straight rifled..
there really arent any aside from its readily available...
haveta mop your barrel, make it shine...
they chop easily, after several atempts to get some of them to fire properly and multiple full cleanings of barrel and chamber still broke like crazy, maybe a setup with a smaller barrel would have better luck or maybe a lower pressure gun, but in my experience with them as of yet theyre not worth it at all, theyve chopped in the chamber and popped in the barrel, if they could break in any way inside the gun theyve done it to me, if only they were returnable...
not so great, maybe another setup would have better luck, but in my experience with them, they stink.
I have a m98 and a Icon E and i can tell you one thing, it doesn't matter how hard the gun shoots, it wont be anymore different with them, you may have had a bad batch because every gun ive used with these they haven't broke and ive played around with low and high velocities with them
maybe they chop because your gun sucks maybe you should go get a gun with eyes i been paintballing for 6years now and i use these paintballs because there cheap and theres nothing wrong with them try them again maybe u got a bad batch and maybe u should get a gun with eyes so they dont chop.
