He used a compound. If I ever draw I will most likely use my hybrid longbow I built or build one just for moose haha. Well it would be hard for me to be picky with a tag like that as well. There is a little bit of pressure along with that tag. I know the guy that shot this bull would of most likely hunted til the last day of season for him before thinking of notching his tag on a lesser bull. I personally don't have the discipline for that and neither do a lot of folks.
As for wet aging, yeah that actually might be something to look into. I have done just that with deer or elk when its not cold enough to hang them but never for more than 4-5 days. I never really thought about. Thanks for the tip!
