I notice your chart conveniently omits momentum readings and downrange energy.
Arthur, I don't know why you use the word conveniently, it should be pretty clear from my post that I'm not playing momentum against KE or the reverse. Like I said, I think for all practicle puposes this is a silly argument to get into and it looks to me like you and I pretty much agree anyway yet I sense you don't think we do. If you like, I'll include momentum in my chart but as far as downrange numbers I said that heavier arrows have more punch at all ranges so I don't get what you seem to be trying to argue about.
BTW, just out of curiosity, why do you always use lb/sec for units of momentum. lb/sec are of course not units of momentum the correct unit would be slug ft/sec.
As far as the 400 grain arrow minimum, I would rather see a minimum on either KE or momentum. Say 35 ft/lbs KE minimum at 30 yards or if you prefer momentum then say 0.4 slug ft/sec at 30 yards minimum. A mass only requirement doesn't take velocity into account which of course both KE and momentum do.
