New Hampshire requires a minimum of 50# at 28" for moose (used to be 60, actually). And I know there are folks who hunt moose with sub-50 bows. I'm not one of them, regardless of the rule.
I need to point out that the bow in my picture above is not the Talon Classic (which is a beauty in its own right.) The bow is actually the one made for my dad the year before he joined the Navy and went off to fight ... the Empire of Japan. :D
Yes, it is shot regularly. For the last eight years now.
