I bought a used Shilen trigger for a Remington 700. Being used it came with no instructions. The weight of the trigger is perfect, but it has a little creep in it. How do I take the creep out of it. I see two adjustment screws...I assume to adjust weight and creep. If anyone could tell me which screw adjusts what, I would really appreciate it. I don't want to accidently change the weight of the trigger...I just want to adjust out the creep. Any information would be appreciated.
