I have a 1972 win mod 70 in 270 win I bought it new. I bought a lighter trigger spring it was the Old Beaver hunting model. I installed it and when I tested it I dropped the rifle on the butt really hard and the rifle fired. I did the same thing with the safety on and when i released the safety the gun did not fire. My question is that if the gun is really slammed on the floor with the butt should it fire, and if it doesnt fire when you release the safety is it ok?
