eightbore,
The set triggers are made to be used in the field, yours may be out of adjustment. You can try turning the screw in a 1/2 turn and see if it helps. This time, you know where you are and can back track, if you have to. I always use a set trigger in the field( if the rifle has one), just don't set it until you are ready to shoot. When set, I don't put my finger on the trigger( I put it on the trigger guard), and when I shoot, I just touch the trigger; after a while, the movement almost becomes automatic. My friend Walter Grass, I often write about him, always said to never set the trigger until ready to shoot, and if you don't shoot, unset it right away. He said it is better to hunt with the safety off and the trigger unset than with the safety on, but the trigger set( of course best is safety on and trigger unset). I don't blame you about the Franz Sodia.
