Model 65M trigger job help needed.

Hello, I have an old model 65M that my brother used 35 years ago to shoot rabbits. He died before his 17th birthday. My Mom pulled it out of her closet the other day and asked me to give it to my boy who is 16 years old.

The rifle is in good shape but the trigger is real bad!! 10 times worse than a 10-22! Does anyone have any tricks they would like to share? I plan on replacing all the springs, as I found them all at Numrich gun parts and do my normal polish job, but any other advice would be great.

Thanks in advance, Dennis.
