Does anyone know a website that gives step by step directions on how to remove the trigger of a ruger m77 to file it down. I just purchased one and the trigger is a little heavy for the long distance shooting I want to do, a few days back I put it in a gun vise and removed the stock but the trigger looked a little tricky to get out. I'm not a gunsmith by no means and havn't had much experience taking them apart. Any advise or direction is appreciated. Thanks.
