The Timney trigger I put on my Howa .223 Varminter seemed OK at first, but now feels a bit heavy. I broke out and followed the instructions on adjustment, but it seemed like I had to move the screw out quite a bit (1/8 in. at least) to get any appreciable difference in the trigger; smaller adjustments seemed to have little or no effect. I don't own a trigger gauge, so this is all by feel. Haven't take the rifle out to try it yet, but I wanted see if those of you who know this trigger can tell me if that much adjustment sounds right. The instructions warn against setting below 1.5 lbs (comes set at 3 lbs. from the factory) at the risks of slam fires. How best to proceed? TIA.
