RE: Check, re-check, re-tune your arrows.
mrfritz44: What you're stating has validity. I don't know the absolute temperatures generated, and it would vary on the material being used to stop the arrow, but I won't shoot into compressed styrofoam any more. A friend of mine had a target bale made of compressed 'fast food' cups. His aluminum arrows, traveling a slower speed, were a little tough to get out of the bale. My carbon arrows, traveling much faster and penetrating more, were almost impossible to get out. When we did finally get my arrows removed, there was styrofoam material 'melted' to the shafts.
