Way to go Oupa!

My rimfire doubles get more use than anything in the gunvaults.
Chances are you'll rarely ever put it away. Mine goes with me all around my place, from up in the attic to alongside the house along the line of cherry and plum trees, constantly pointing up into the giant avocado tree plinking squirrels and out in the machine shop keeping the rat and pigeon population down to a bare minimum.

Don't spare a moment on metal finish work.
File the hell out of it.
You won't have to worry about thinning the barrels or action too much.
Post some photos when you're ready to show it off, and for the Good Lord's sake, have a blast and a half with it!
