8Ball, is the bore good, or did it have rust in it? Mine had the protective cardboard rod in it, but it also had some red crap in it that turned out to be old preservative grease. Once I got that stuff out of it, it had a beautiful bore.
I have only shot it at 50 yds, with the iron sights that came with it.
So far, I've shot some old Hansen std vel, Win Super X, SK Match, CCI Green Tag, Fed GM Ultra Match, and RWS-50. (The Fed UM and R-50 are about $18 for a 50 rd box, unfortunately). All groups were 1" (2 moa), or worse except the RWS-50, which consistently shoots 1/2" five shot groups (1 moa @ 50 yds). I am positive that I am the limiting factor, and will never know how good the rifle might be without mounting a scope on it, but I enjoy shooting the iron sights and may never scope it.
Another factor may be barrel seasoning. I only have 60 rds through it, and I believe it's getting better the more I shoot it. Also, I'm up to 5 rds between cleanings now. Maybe some of the experienced rimfire shooters like Solyanik can comment on this. I'm not positive yet.
On the stock scratch.....I was told that a lot of the 82 stocks were cut by a boxknife when the CMP nitwits were cutting the boxes open.
I'm not a fan of single-shots, but I really like this rifle.
Good luck with yours. Tom
