They are hard. so if you're trying to hurt somebody it might help.
Too hard - they bounce
These are the must innaccurate paintballs i have shot to date. now i usually shell out the extra few bucks for better paint and i guess this is why. they were fine at close range but once i got up to about 100 feet, you couldnt hit the broad side of a barn, with either gun. they would zing off in either direction at the last second before impact, some of them would dip down and pop up at the last minute, and i dont mean a small dip and a small pop, were talking 5 feet each way. they arent prone to breaking in you're gun or barrel, (although i did break one in the flatline) but if you plan on playing back, or making any sort of long shots do NOT buy these. they are good for screwing around at about 25-40 feet in your back yard, or to use at the chrony. before the end of the day, I was giving them away for free.
Bottom line, i would not recommend this product to a friend.
