A few years ago my father in law gave me a 22-250 that he built (had built ?) around 1964. It has a Mauser action and a huge heavy barrel that he said was made by Hobaugh Rifle Barrels out of Montana (he thinks ?) It is a right handed bolt and i'm a lefty. The big heavy wood stock on it does not fit me well at all so i'm thinking of putting it in a new stock that is more lefty friendly. Anyone familiar with these barrels and also how can i identify what Mauser action it is ?
