Pellet gun, pellet gun, pellet gun.....
Guess what I can make a "495 FPS" pellet gun shoot at over 700 FPS. You want to know my trick? Using hyper velocity pellets.
FPS means NOTHING. NOTHING. It NEEDS to have a mass associated with the speed, otherwise I could get a paintball marker shooting at something that makes it illegal, make an airsoft gun shoot "hot" with .12's, or using a hot airsoft gun make it shoot under the "limit" with a .43g BB.
nothing has changed in fact the law is been spelled out more concretely and there is now precedent.
