I got my self a nice little Remington model 25 in 25-20 with a barrel thats completely pitted through out the bore and needs to be re-barreled, I got thinking that instead of getting a new barrel installed on it I would get it rebored out to a 32-20. Anybody know who would be able to do the work on it and approximate cost on doing it? I have to do a little more research on it before I get it done too, this one is a little different than the other model 25's I have. Right above the serial number it is stamped AA. Not sure what that means, any one have any ideas on that? Thanks again.
