first of all I know the difference between to 2, but my Santa Barbra Model 1000 chamber in 308 win has 8" center to center on the action screws and 3.25" in the mag well, there was a spacer in the mag but it fell out, it doesn't affect feeding at all works fine. So would this be a long action? It is a commercial mauser action, same as the parker-hale and I would like to rebarrel to a 35 whelan
