RE: 400gr minimum in PA?
the wifes shooting 420 grain arras out of her 40lb bow, more then adequate for killing big game in Alaska. Obivously she isnt pulling enuf to hunt moose bison muskox elk and mt goats but what she can hunt she could kill!
As for the arrow weights and cranking a bow down....punch numbers down range, you would be suprised what you find at 20-30 and beyond as far as you KE and Momentum both! Your KE is going to be effected more obviously as the momentum is kinda a by product if you will.
Saying it will limit women and children....I dont think it would, however I do agree they should be on the higher end of the weight per pound of draw to acheive maximum penetration.
There is however more to all of this being penetration is the hole goal here! Arrowflight, type of arrow, broadhead design, all play just as much of an important factor as the weight, KE, or Momentum does. Maybe what we should be asking for is more education by the folks at be who know the figures and can sit and put the hard numbers on your plates instead of posing more rules. Being knowledge is the key to success is it not.
I still think if they are going to try and mandate something, arrow weight shouldnt be it....grains per pound of draw should....if you are under by as little as cyclone said, I dont see where jumping up 10 or 20 grains in weight is going to hurt more so where it is going to help in your 'quests' to maximum penetration. It targets more of the folks shooting setups way below whats already recommended! Throw in mech heads and you have a hole nother ball game (ie more numbers and figures to....figure out!). Should we be limited by these figures....I can say we wouldnt if more people understood them but more importantly maintained them!
