Take your stock springs and remove a ring at a time until you get to the desired weight. Had a guy show me how to do that on my Browning Stainless Stalker in 30-06. Brought the trigger pull from 8 to three pounds. Always test the unloaded rifle for safety when lightening the trigger by hitting the butt stock on the ground to simulate falling off a bench to make sure the trigger isn't too soft to cause it to fire with the safety off.I agree about the safety with a light trigger pull if you are carrying it around and/or hunting with it. I plan on just using mine for target shooting off a bench and possibly shooting benchrest in competition. So I will change out the trigger spring to get it down to around 1lb trigger pull or so. I will have to experiment to see what works best for me.
I use to compete in 3 gun and GSSF matches. But I am getting older and ready to slow down a bit. Precision Rimfirre shooting might must be the thing.
If it doesn't work, you have the options given above for other replacement springs.
