Why dont you get some of that CSI stuff and use it around where you butchered your deer. You would be suprised. It takes very few molecules to activate the reagent. So few in fact that the blood is not visible. This is how murder scenes are determined.
Hyperbole on the Pro lifers, a little, but I do not doubt the test results.
Surely you are not suggesting an alteration in my Gun Show budget!?!?
