I'll relay a true story about adjusting Wichester 70 triggers. I generally stay in the shop during deer season. Not a big deer hunter anyway, if I'd take one I'd have to gut it. Anyway, it was about 10AM on the first Saturday. The phone rings: "Do you work on Winchester 70 Triggers?" Sure do. "OK, I'll be there in 1/2hr. to 45 min." The guy and his buddy show up at the shop and I remove the barreled action from the stock while the owner tells his story; "I was leaned up against a big oak just watching to world go by. About 175yds. out the biggest buck I've seen in years stepped out of the brush, a nice 12 pointer and big bodied. It'd have been a clean broad side, in the shoulder shot. I flicked off the safety and blam! Earlier in the year I had a friend adjust the trigger on this rifle. I don't know what happened. Good thing I didn't have the muzzle towards one of my feet when I flicked the safety off, they'd be calling me Stumpy". I gave the trigger a quick look see. His 'friend' had adjusted the trigger return spring to the point that it wasn't even making contact to reset the engagement after the trigger was pulled. As long as the muzzle was pointed down, gravity would reset it. The guy had probably pulled the trigger while the muzzle was pointed up and there was no spring tension to reset it to the proper position. I set the trigger pull to a solid 3#, as he requested. His recent experience had really put a scare into him. The rifle was chambered in .300 Win. Mag.! Could have been his last hunt!. Moral of the story,,,, make sure you know what you're doing when adjusting any trigger so you don't have a "last hunt" because of a catastrophe like this guy narrowly missed! Factory triggers will never have the qualities a good after market trigger will, when properly installed and adjusted. "Drop-In" isn't always so, but makes a good selling point!
