Not knocking you too much pal, but I wouldn't dare sue or expect Sako to be responsible. You didn't have the gun pointed in a safe direction with live ammo. Broke a golden rule.
When I adjust a trigger, I work the action well over 20 times, very hard and very fast. Without ammo. I then load it with live ammo, and have the barrel pointed in a safe direction (not towards walls, people, or vehicles, maybe my wifes dog
). I then work it a few times. Even after that I don't fully trust the trigger. Confidense if over time.
You can tell I have adjusted a few remington triggers.
