I have a Stanley 271 but never thought about using it for inletting gun stocks. I will have to give it a try sometime. I can see where it might help with locks and sideplates. I did use a Montgomery Ward #45 when I started out, for cutting the barrel channel and ramrod groove. Then I either bought or made traditional wood planes for those purposes. I have a period gunstocking plane that I use for roughing out the barrel channel. I made a little plane, actually two, for cutting the ramrod groove. The initial groove is cut with gouges, though.
