If you play on a field run by professionals, they'll have a radar station set up and you'll be required to have a much lower velocity before you're allowed on the field. 250 ft/s seems to be a standard. However, some of the custom jobs get much higher, in the 350ft/s and high range. A .45 it about 425-450 ft/s. Of course the projectiles are much different, but I've seen some really nasty injuries with paintball guns. Even with protection they can leave welts.

.45 acp is more like 750-950 for +p rounds...
