Not geeky mate as knowing history makes for more understandingGeeky boring paintball fact for you, we arrived at the 300 fps limit for paintball when some of the industries founders (I think Tom Kaye was involved) asked some doctors what would be safe. They suggested any more than 300 would likely break fingers if shot up close so that was taken as "safe". Before that most times you shot at a tree to check your marker wasn't hot, the determining factor being how much bark it knocked off.
Now my part was geeky
