Well, I don't know if this is in the right place so if its not, somebody please move it to the right place. I have 2 H&R 12 ga single shots that I would like to revamp and modify. By modify I mean I wanna cut there barrels down to 18 1/2" I believe that they have a full choke on them currently, they don't say and aren't threaded. If I cut them off will I be able to run slugs through them without the threat of them blowing up in my face? Next question is this. How easy is it to cut a shotgun barrel? Any help on the second question would be appreciated.
