Hi all. A while back I restored a Savage 430. Although I know this type of gun is not generally the kind discussed here, I'm sure many who have owned one of these would agree that they a pretty nice little guns. Anyway, my gun is a 12 ga and I've got the crazy idea to fit a set of 20 ga barrels to it. The poor man's two barrel set if you will. I've determined, through research, that frame sizes were the same for the gauges offered. I've obtained all the needed parts from Numrich (forend, fe iron, spring, barrels, etc) and managed to mess my first set of barrels up. At only $59 for a NOS set I'm not out too much.
Anyway, to get to my question, what exactly are the basics of fitting a set of barrels ? I'm familar with smoking the breech end to get a final fit, but a little uncertain of how to file the hook to the exact diameter of the hinge pin. The NOS barrels have the hook on the lump started but it is no where near final size. On my first set, I filed the hook too much. I got the barrels to fit, but they do not lock up tight. My thought is I need a file the same diameter as the hinge pin and with that I can begin slowly filing the hook until I get the barrels to rotate in.
I understand that I will have fitting work to do on the FE iron and perhaps in other areas, but this is just a fun little project to attempt. Any suggestions from anyone who may of done this before would be greatly appreciated.
Thanks
Vince
