Albino deer are not a protected species in Missouri. What a chance at a unique trophy. With a firearm I'd bust him through the front shoulder. There would be an easy blood trail with all that snow.
With my bow I would wait until he went back to eating those yeller acorns and get a broadside shot when his left leg is forward.
I would take aim and drop him, that would be an awesome mount to in my trophy room. I have hunted for many years and have never came across an albino deer so it would be a trophy of a lifetime.
