Thanks! I had my Judge for about 5 years and shot boxes of the standard 45 LC (Cowboy Action Load) and a variety of 410 shells without any problems. Keep it cleaned and oiled. Had not fired it for several months prior to taking it out this time. And yes, I tried the failed rounds again and then one more time just to make sure. I cannot tell any difference in the firing pin impression between these rounds and the ones that fired correctly. Maybe Abby at NCIS could. That's why I was suspecting the ammo. I'll get me another box and try again. Will let you know how it turns out! Since you are an instructor, what really surprised me was my reaction to the gun not firing. I was TOTALLY unprepared for that to happen and actually froze for a few seconds when it happened. Next time I am going to the range I will only put 4 rounds in and spin the cylinder (like Russian Roulette)
to improve my reaction if it only goes "click".
