Here's a pretty straightforward video showing improvements that you can make to a rifle that doesn't seem to be as accurate as you'd expect. It's too basic for any of you competitive or long range shooters but I'm just a hunter so some of the stuff is new to me. For example, I never knew what "lapping a scope" meant. Always sounded a little kinky to me. And I've never paid any attention to how you might go about developing a rifle-specific load.
If you're in a hurry or have a short attention span, you might want to skip the first 4 minutes. It's mostly backstory about how the previous owner couldn't do any better than a 3 MOA group and, like most hunters, concluded the rifle was a POS and got rid of it. Pretty nice set-up by the end
