Sorry I put this in the br forum, my thumb was aiming for the ppc forum.
I decided they were worth $750
More to Ruger honks, than target Shooters.
I believe you are in the ballpark. A couple of years ago I sold a 6PPC in nice shape for $825. Mine had approx 450 rounds thru it and shot in the low 0.4's. I believe Ruger used Douglas barrels for their PPC's.
