I've shot enough of the M77s to hate them. They are not up to par in the accuracy department.
Before people start to jump on me about my comment, I've shot 20 - 30 of the things and hundreds of rifles in the past year. I'm not saying that they can't build an accurate rifle, but they as a percentage wise are less accurate than your run of the mill Remington 700 or Savage 10.
I shot a M77 the other day and the trigger was horrible. It was bad enough best group I could get was about 2.5".
