i've only shot them with my mag and cocker, one with a dye aluminum and a dye boom, the aluminum was a little big for the paint but it still shot realy well. they are a small-medium size and the shell is brittle so i've had very few, if any, bounces.I cant say enough good thing about the fill, its realy bright, easy to see, and hard to wipe. my friends have shot it with their angels and even a tippman, and they all love it. My best advice is to order a case your self and try it out, for $40.00 a case you can't beat the price. or call them, i think they were sending out free samples of like 10 or 30 balls (i may be wrong) just try them your self if you don't like them the worst that happens is you never buy them again, but think you won't be dissapointed.
