My BIL and I got to shoot some, before the match was rained out. He shot some of my reloads through his Taurus PT111. He had three rounds in a row that failed to fire. He set the rounds aside, and later we checked them.....all three had solid primer strikes....the primers were just dead. At first, I thought they might be light strikes, but no...the strikes were solid. Has anyone ever experienced this with Win primers?
