My mzl is old and I've never fired it. It is closed breech so I wasn't site hoe to clean it so I haven't cleaned it yet. I was reading earlier that rust can cause a type of obstruction. I was going to clean it but I had never heard this. Also, what about pitting? Someone had written on here that they had to retire a mzl because the barrel was pitted. When is a barrel to pitted to safely shoot?
