Bloodying a rifle...
or a bow, crossbow, shotgun or whatever you use for hunting.
Is it important to you to do this? It is for me.
Perhaps the best part of my Montana hunt was that I bloodied my .358. I may just put it away and never use it again, but I'll know that I've taken with it.
Gun control laws make about as much sense as taking ex-lax to cure a cough.
