I have always wanted to put a new barrel on a rifle , but I usually work out a decent shooting load and this stops me from doing it . Hopefully this will happen again with my new project , but only time will tell . I have a lot of questions about changing the barrel on mauser small ring receivers - I suspect a few gentlemen here may have done this in the past . For a wile I have been doing a little research on this , so now I'm really confused . It seems to simple to think I can just purchase a pre threatened short chamber barrel , screw it in the receiver , then finish the chamber to headspace it correctly . Is that kinda all it is to it ?
