I had a sendero in 300 ultra mag and the trigger was just like the one in the picture. That trigger adjusted down nicely. I adjusted the sear engagement until it went off when the bolt closed then backed it off a little. Then I dropped the but of the rifle on the floor several times to make sure it wouldn' t go off. Then you can adjust the other settings to your liking. Dropping the butt sounds bad but mine was a rubber recoil pad and I wanted to make sure it wouldn' t go off if it were dropped or bumped.
