Trigger jobs are pretty easy on Remington 760s and those with similar trigger groups. Knock out the (2) pins, and pull the trigger group out the bottom. Eyeball the sear engagement. I cut 'em(hammer notch) with a file to lessen engagement (and creep). .030" will be about right.
Too, there is a coil spring that fits over (2) tenons that provides trigger return tension. Its the obvious one, and come right off. Cut (1) coil and try before removing more.
Reinstall the spring, reinstall the trigger group into the receiver and check to see if it suits before going too far. Trying to check with the trigger group out of the receiver is deceptive. If you cut the sear notch on the hammer too shallow and cut the spring too short, it can make for an unsafe condition.
