Black Powder firearms and muzzle velocity measurement?

[severnsider]

you can shoot over a chrono but it must be a distance away from the muzzle or you shoot throught a paper screen which is in front of the chrono...... i prefer the first option.

Thanks for that Stephen. It would seem that both these options could be used by a prospective shooter to demonstrate to the RO that he's within limits then.
