Nice read mate!
I'm a serial tinkerer, if it were me I'd have it stripped, de-burred, smoothed and polished and relubed.
I recently done a .177 Stoeger X20 of all things and it made a hell of a rifle out to 40yds and I put this in the same category.
In that respect Im thinking of making a "sleeper" as a new project..... Get a budget rifle and tune the cr*p out of it to make it a hell of a smooth accurate rifle then surprise the crap out of people when they shoot it.....
