For a shooter, consider the 24/47. They were re-arsenaled before being put back in long-term storage, and many were never re-issued.
We just got one, and I know it was never used after, because the bolt safety did not operate properly, and the rear action screw was too long and it was impossible to run the bolt. Both of those are easy fixes, and the barrel on it appears to be brand new. Not so much as a single pit or sign of wear/use.
