I just purchased a stainless Ruger Old Army from a local gun store. Unfortunately it came from an abusive home. The barrel is very rough inside making it difficult to clean. It seems to shoot okay. We have located a new takeoff barrel and would like to replace the old barrel. How would one go about taking off the old barrel and putting on a new one without harming the firearm, and then indexing the new barrel correctly.
The cylinder is very rough as well. Does anyone know how deep it can be reamed out?
Thank you for any advice and wisdom you can send our way!
