I'll have to check mine. Funny thing is that, during a recent range session, I had two misfires of sequential rounds in a revolver with this stuff. Never had a misfire with this ammo before. However, I had never fired this particular revolver, an old (Interarms-vintage) Rossi M68 before. Dozens of other WWB rounds fired in the gun, as did the two misfired ones the second time they were tried.
