Agreed... I’m so not impressed with the 770. The Savage is quite the rifle though and the trigger is reasonably easy to adjust. :-)
Why on earth would you want to lighten the pull on a hunting rifle? This renders them dangerous to carry in the field. Most 6 to 7 pound standard pulls are there for safety and are still adequate to make a good and well placed shot.
Tampering with any sport/hunting rifle is stupid as explained above, as well as completely unnecessary.
Unless you are a tournament shooter, shooting from a bench under tightly controlled range instructions and rules, don't even consider rendering your hunting rifle into something very dangerous, by “adjusting” the trigger.
