I have a Rem 510 single shot. The trigger was heavy when I got the rifle so I did the following. I removed the trigger spring and cut a couple of coils off of it checking the pull weight as I went. I did a good clean and lube job on the entire action also. My pull weight is now at a measured 3 1/2 pounds. The break is somewhat crisp. That rifle is my go to 22 LR G-hog rifle. Many critters have fallen to its report.
