A 1) Crossbow use in your states archery season.
A 2) state imposed antler restrictions.
A 3) 223rem for deer hunting(within reasonable range).
F 4) headshots on deer (past 100yds).
F 5) legally killing animals you dont intend to eat.(meaning unedible game- yotes,coons,diver ducks, etc....)

Some of these are fuzzy...

Antler restrictions in general are ok, but when you have a 10yo deer with 3pts that you can't harvest because it would be illegal, you should have the right to take that buck, I'd support some guidelines to help improve trophy bucks instates,

ie...avoid taking button bucks.
try to only harvest 2.5+ or 3.5+yo bucks...
spread past the tips of the ears...
also young management bucks should be able to be harvested, ie 3.5yo etc...who are never going to be big bucks, 3x3, should be able to be harvested...
of course property management goals etc...could override many of these...if need be.
