I was wondering if any of the loonies could identify the gunsmith from the caliber scribe on this rifle? It's a little more elaborate than I see on most rechambers. I bought this rifle off Gunbroker but haven't had a chance to try it yet. I can't wait to start forming some brass for this great improved classic on my favorite platform - Ruger M77 Tanger.

P. O. Ackley, the gunsmith that originally developed the Ackley Improved line of wildcats.

Just so I understand, are you saying that scribe is Ackley's and he is the one who rechambered this rifle? Thanks.
