There is no need for a state wildlife agency to regulate draw weights, it just complicates regulations and is rarely checked or enforced. We did away with them in KY in 1997 -- no problems. Bowhunters want to be successful. There are far too many regulations on the books in many states that have no impact because they are unenforceable from a practical standpoint. They will educate themselves (and the reg. guide isn't their education material) enough to have a chance for success. Frankly, (while it would be silly and unenforceable)it would make more sense to regulate agains quartering forward, running, and shots beyond a person's effective range.
Such regulations (min.draw weights, cast, broadhead widths, etc.)reflect opinions and biases of small numbers of people influencing a game commission that doesn't know better.
Do I think a bowhunter should be thoughtful and take care not to be under-equipped in the field? Absolutely! Personally, I'd be glad to walk the isles of the sporting goods store and throw several broadheads to the floor -- but all of them have and will continue to kill critters. If a person isn't at least 75% confident (very low) of shots at certain distances on targets, they have no business taking such shots on game -- but those are my preferences and ethics and I wouldn't expect others to conform to me.
I don't mean to be ill towards anyone here, especially not archery organizations or game commissions. I'm a life member of one, measurer for another, and have worked game commissions for 30 years in four states.
