Excellent point. Definitely something that needs to be considered. After thinking about it a bit more, the bb is at rest within the hopup, in contact with the bucking/nub, so that means that its velocity is nearly zero when in contact. Good news for me I suppose.

I think I can gain access to a wind tunnel, but what theory would that be? An easier experiment would be to drill a hole in the center of a bb, and use water flow and dye (attaching the bb to some sort of motor)

I'll try getting some footage on Sunday when I test out my new batch of nubs.
