I just got back from the range where I brought my S & W 686 plus, and used the range's magtech .38 special ammunition. It was a little frustrating because 2-3 rounds out of seven would not fire. the gun just clicked when it got to those non-firing bullets. is it the gun's fault or is it the ammunition? This was my first time firing this gun. I went through 50 rounds this way, having to pull-out and throw-away the ones that did not fire.
