Forget the Timney Trigger(14/05/2016)
I installed this sear/trigger spring in under 2 minutes, one pin to knock out and reinsert and that's it. This makes that very stiff Ruger M77 trigger that everyone says can only be fixed by an aftermarket trigger a dream to shoot. Mine pulls dead on 3.5 lbs. now and has no creep at all. I was about to buy a Timney Trigger and decided to try this first for $110 less, and it's an amazing add on for any rifle. I would highly recommend this to anyone.
Installed on 77/44. One pin after you get barrelled action out of stock. Replacement spring is longer but definitely weaker than OEM spring. Adds a bit of creep or take up to pull but it reduces the amount of force required to trip the firing pin. Not as light as I would like it but better than it was.
