Don't know if this helps but in 1970 I bought a new Ruger M77 short action with the old tang safety. After about 100 factory rounds, wasn't satisfied with the trigger pull and, being a starving USAF E-5 with our first baby, decided to adjust the trigger to improve the let-off myself. Got it too light and, upon working the bolt smartly, put a 100 gr Norma factory round through my ceiling/roof. After scraping my wife off my back and changing clothes, I readjusted the trigger back for a heavier pull and I've never had a problem since. Recently had the gun worked over by Hill Country Rifle as part of their accurizing service and I'm very satisfied. Nothing wrong with the Ruger trigger, just some Ruger owners.
