I shot some arrows into granite and cement last week at 12 yards with no arrow damage. I'll try and get some pics up. Kevin.

The only wood shafts I ever had that could take that kind of abuse were the old compressed Forgewoods. This should be interesting

If they are properly tuned, I wouldn't recomend doing it again.  They could have hairline fractures that will not apear till shot again, and I would hate to dig that splinter out of my hand, and not to mention, a properly tuned arrow will bounce directly back to where it came from.  I'm not a betting man, but if I was my money would say it would probably suck to pull an arrow nock out of your eye.
