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?
Just changing the spring will actually make the rifle less safe due to the design of that particular trigger - as you found out by doing this silly 'drop test'... Keep the rifle on safe UNTIL you're ready to shoot it.
The safety actually retracts the firing pin from the sear, so your new spring will have no effect on taking it off safe and having it fire.. That wonderful trigger can be made to be perfectly safe down to 2# or so with a proper re-work/refit.. I only advise that a weight that light should not be used for cold-weather hunting where the owner's probably wearing gloves.. In that scenario, it's best to keep it at about 3#.. But once reworked you'll experience nearly zero creep and it'll let off nicely..
