Is there a thread on this somewhere. I seem to remember they can be adjusted, but I don't want to mess with it too much till I know a little more. It breaks clean but the pull is about 7 pounds - way to heavy. I'll go aftermarket if necessary. Nice little rifle, terrible trigger.

Noooo, don't go aftermarket - IMO, the old Ruger trigger is one of the best. Easily adjusted.

I have had several older Rugers (still have a couple), and have worked on several for friends & co-workers. They have a totally adjustable trigger - the little screw in the trigger (that you see looking at the trigger in the trigger guard) is the least of important of the 3 available adjustment screws. First, instead of stoning, it has an adjustment for trigger-sear engagement (take the action out and you'll see it going into the top, front of the trigger). You can polish the sear bearing surfaces, but there is no need to really "stone" them (unless something is out of square, but I have yet to see that). Then, there is a set-screw that has to be removed (in the "housing" in front of the trigger) to access the over-travel adjustment screw - pretty self-explanatory when you look at it. I get the trigger adjusted nice and crisp with the screw in the trigger backed off almost all the way (basically just holding the spring in place with enough tension to "reset" the trigger). It may take several attempts to get the trigger-sear engagement set to the minimal that is safe (returning action to stock and testing by slamming bolt, pulling trigger with safety on then moving safety to off, dropping on its butt end with safety off, etc.). Then you can adjust the pull weight up with the screw in the trigger - for example, as light as possible for testing handloads at the range, then tighten the screw to increase the pull for hunting.
