I usully butcher the animal per usual setting aside the heavily bruised or shot through pieces for special attention,depending on the damage,some goes into the trash. Heavy bone trauma will produce a lot of waste,but I can save a lot by trimming to within 1/2 " of the area. If the tissue is just blood shot it will rinse out,after soaking for several hours,you may have to score a little it with a knife tip to help release the coagulated blood.When you butcher your own animals,deer or what ever,you will learn not to hit them in the shoulder or the hind quarter, and use a bullet that will hold togather.
