Rust on new Beretta 410
hi everyone. I have a new Beretta 686 .410 and have been using it daily for the last 2 months. ive been cleaning it weekly with boresnake and wiping the action and adding a little tetra gun grease to pivot points in the action and smoothing a thin layer in the contact point area. I’ve also been wiping down the barrel with eezox to keep a layer of oil on the metal.
This rust is developing and I don’t know why. What should I be doing to prevent it? Will a brass brush and CLP remove it?
