A few weeks ago I bought a Smith 66 with a 2.75" barrel new from a gun shop not far away. I took it home and sighted it in and put another 50 rounds through it. After maybe 200 rounds through it I got a double action light strike. I thought maybe the primer was a little proud and I missed it while loading the revolver. I have had multiple light strikes with this revolver over the next 100 rounds. I checked the strain screw it was maybe a half turn from all the way in. The reloads I am using run just fine in my 686 no dash so I am quite certain it's not the magnum pistol primers that I reloaded with. A local gunsmith that has retired to everyone but close friends will be home from Florida in a week and I am going to let him look at it. Any thoughts on things to check before he gets home. I feel like the old you always get 6 out of a revolver is getting shattered lately.
