I wack a cow each year in addition to my bull.
And try and shoot a young cow,
the method that has worked for me is
don't shoot the large sized (grandma cows) and don't shoot the small sized (young of the year)Pick out a middle sized.
A little less meat but a 2yr old cow will
always melt in your mouth.
you'll know you've done it right when the ivories are still hollow, like a spike bull.
