I was out at the local range a few days ago and a group arrived and took the shooting bench next to me. Nice folks, very polite, but shooting very high power loads with a muzzle brake. I had a note paper on my bench with sight settings. Every time they fired the rifle the muzzle blast would blow the notes off my bench. It got me to wondering what the proper ethics are for using a muzzle brake at a range. I know I am exposed to lots of things at a range, but not sure I like breathing the muzzle gas of the guy next to me instead of it going down range-- or getting blown around by the blast. I was shooting cast loads (not too loud) but had to push the ear plugs in extra deep to put up with the blast of the guy next to me.
