Being used to iron sights, I almost
shot my chronograph when I helped a friend with some handloads for his scoped .243 rifle. I had the chronograph held on a stand with a bungee cord. When I was done shooting, I noticed that I had clipped the bungee cord with one of the shots. There was a black streak on the top of the chronograph where the bullet went, but no actual damage. It doesn't get much closer than that. The black mark is there to remind me to be more careful.
