Flatout,
There may be other requirements for archery hunting of big game besides minimum bow poundage, that you should be aware of.
In Idaho there are several requirements for hunting big game (all big game species) with a bow, they are:
1)Bow weight minimum of 40# at a 28" draw length
2)Minimum arrow and broadhead combined weight of
300 grains.
3)Broadhead minimum width of 7/8 inch and
primary cutting edge minimum of 0.015 inch
thick.
FYI, no requirement to date for distance or
cast of an arrow.
I hope this helps. Best of luck.
