Sometimes there is an excuse for cheap ammo. The course of fire as announced stated that there would be no rifle shots over 65 yds. As long as the ammo would cycle reliably just about anything will work at 65 yds.
I thought I knew better but completely forgot that my cheapo Wolf ammo might be steel core. A very strong suggestion prior to the match that the shooters magnet test their ammo is a cheap way to save some plates.
I guess I should have said ammo of unknown components.
