If I felt as uneasy as you do about it then I wouldn't reuse them. I'm only shooting @ 350 fps out of my bow. I wash, inspect, and reuse my arrows as long as they look good. At first I didn't, but the vase got full and I didn't have anywhere else to save my "trophies" so I started reusing what I could and throwing away what I couldn't. I have killed 3 and 4 deer with the same arrow some times. Other times they are damaged first time.
