If we're going to be this nit picky then you'd also need different velocities per weight going beyond a simple joule conversion to account for the difference in inertia/momentum. 6mm BBs of varying weights deal with this dilemma and you don't see people advocating higher limits for smaller weights to compensate, reason is because muzzle velocity is the accepted standard.

You open the door for now debating at which range velocities will be measured, as muzzle velocity will no longer do if we're going to get into specifics about the changes during a given BBs flight. Not so much for where to test individual replicas to make sure they conform, but instead, where you set the standard; what distance are you going to choose as a model of the average engagement distance?

Only muzzle velocity works as a true safety standard because it is the highest possible impact velocity.

I'd rather have safety standards set on the worst possible scenario than the average experience, which in this case would be arbitrary at best.

Thanks for posting the numbers Junto, I updated the safety rules with separate sets of limit numbers for 6mm and 8mm so there won't be any confusion in the future. Like I said - the rule has always gone by output of energy in joules, regardless of BB weight or size.

Yeah, I guess that's easier, anyway.
