I attempted to remove the ejector retaining pin from the bolt head of my Mod12 action. I read Boots McGuires How- to on the subject. I watched several Youtube videos. I used the proper sized punch. I tried to move the pin from the small pin hole side to the side with the dimple. The pin moved on my side of the head, but did not move on the dimple side. Did the pin break? I only tapped the punch with a tack hammer. I switched to a cut allen wrench that fit the hole, but no movement of the pin on the opposite side of the bolt head. Anybody have any ideas on what may have happened? Where should I go from here?
