they absolutely will not break,i use a dye excel i went through like 2000 and not one break in the barrel. they r pretty accurate and have a nice spin on the ball.they look pretty nice too.
Weaknesses:
they could be alittle more accurate ,but that just might be my aftermarket barrel.cause other than that there awesome ass paintballs.and there is really nothin wrong with them at all.
Conclusion:
these paintballs are very good,u can get them almost anywhere,and there pretty cheap,not too bad. most paintball places ive been to use these as the required field paint.
