I have never had a drop fire with the .040 piano wire springs have them on 3 different rifles , right at 2 3/4 # on them. Have one rifle that has a .037 wire spring it is a little light . I am the only one that shoots it , and then only at paper for that one.Sear engagement angle on the savage can be real critical . A little off and you will get the drop fires . A little polish does a lot. Bought a couple of Savages' pretty cheap after someone else screwed them up them .
