I don't really play fields very often, so my buddies and i don't really buy tourny grade balls to go out and play in the woods. We picked up some hotbox balls to go and play some woodsball in my friend's backyard. We all have different guns and different barrels and i swear, every single one of us had a problem with these balls. They break, they go everywhere but where you want them to go, they are just plain aweful.
Conclusion:
do not buy 'hotbox' balls. i was shooting 10 balls to hit the same target that would take 1 ball of a more expensive paint. I've learned my lesson, if you want to have a good game and actually hit what you aim at, DON'T BUY THESE BALLS!!
