I recently bought a box of Hornady Critical Def. ammo.(.357 mag) and tried to fire it from a Ruger Security-Six (4"with a prefix of 150.....) made in the early '70s. The first round was a FTF (tried 3 times) and the second round fired but locked the cylinder up because the primer had a raised "pimple like" mark in the center which would not allow the cylinder to rotate or open. I eventually got it open and sent the box of ammo back to Hornady for investigation. The ruger shoots .357 hydra- shocks and cheaper .38 ammo just fine. Has anyone else had this problem with the ammo? or could it be the gun? Any info. would be appreciated.
P.S. I should add that the FTF had a nice deep impression in the center of the primer.
