Has anyone reduced the trigger weight of a savage accutrigger before?

I believe I read anyone can reduce trigger weight with the tool they provide, the question I have is getting to it, I assume you have to remove the trigger guard, but if you loosen up these screws do you completely mess up the bedding job? I've never done this so I'm not exactly sure how this works?

I've read you can reduce trigger weight down to 2.5lbs, factory set at 3.5 or 4lbs, I have to check the actual trigger weight.

Any advice would be appreciated.

I believe the savage 220 slug uses the savage 110 action.
