Some guns hit the balls a little bit harder than others, that so at the moment most NEW guns hit the balls that little bit softer but still keeping the power for the balls to travel , and in turn not wasting air, however there are guns out there that are fantastic value for the money like the Planet Eclipse Etha, now this hits the balls a little bit harder and was designed for the Woods, Woodsball guns usually hit the balls that little bit harder hence the balls having a slightly harder shell so it allows them to get through bramble and foliage, these Paintballs are of the Cheaper Price, Now if you have a ( what I call a Pro Gun ) more or less up to date Tournament gun , then you will buy a dearer paint that will guarantee a splat when you hit a person, you see my friend your trying to eliminate the bounce factor and know your going to get a kill every time it hits them, these balls you can just put out your arm and drop them and they will splat, the others for the woods, you will need to throw them. and for this you pay accordingly.
