First a little background and then a question. I own three relatively new Savage actions, several stocks and several barrels I can mix and match as needed. I have two short actions (12FV, 12LRP) and one long action (114), everything push feed. The 12LRP requires a 1.120” large shank barrel being based on the target action and the others take a 1.055” standard shank. I recently picked up a 270 WSM 26” large shank stainless barrel and a similar 300 RUM in standard shank and thus I needed a few more magnum bolt heads. I got one for the long action and one for a short action and I already had one for a short action (7mm WSM). Though I got the second short action bolt head from the same source as the first one, it is not at all the same. The one I have on the 7mm WSM measures 1.439” long and will work on either of my short actions. The new one has the same shaft but a thicker bolt head and consequently measures 1.543” long and will NOT work on either of those actions. Being so much longer, the firing pin can not be adjusted to protrude through the hole in the bolt face though it works otherwise. This is a Savage factory original complete bolt head. So that brings up a question or two for the Savage experts out there. What the hell is this thing, or better said, what Savage rifle does it fit? I plan to pull the parts off this bolt head and install them on a new PT&G performance bolt head so I’m not stuck but I am curious as what this could be. Until I opened the package, I had no idea such a thing existed. It is between a long and short action in length as long action bolt heads measure 1.620”.
