@lsb-gunsmith I see on the website they have shotgun and rifle. Which would you recommend for pistol? Are you ever concerned about the chamber where it headspaces? Again I appreciate your advice
@timothy-evans I used the .44 mag chamber brushes. I like using them due to they move the metal more the it cuts the metal. You do have to worry about headspace, but as long as you don’t ram it hard and repeatedly into the front of the chamber, you will not change head space. Definitely want to use their oil for the process I run a cordless drill on high speed for about 15 seconds. Clean every up and inspect the chamber. If it is a deep scratch you will never remove it, but can make it smooth enough to extract in a auto action. Slow going is the key. You are only polishing and not reshaping or cutting the chamber. By polishing I mean you are not removing enough metal that you can measure with readily available precision tools.
If anyone is having problems with your Auto Mag please contact us.
