I shoot lots of stumps and my area is not arrow friendly. The stumps are hard and the woods has rocks sticking up everywhere. Just for the heck of it I started counting how many arrows I break or lose in a year.
So far in 2007 I have lost or destroyed 58 arrows! And I still have 8 1/2 months to go!
It's a good thing I love to make wood arrows. I scrounge up cheap shafts at swap meets, use dowel rods, buy seconds, etc. I make them cheap. Money well spent for the enjoyment I get out of it.
