Despite my best efforts to mitigate it, at least two of my surplus rifles have now developed pitting in the rifling grooves from shooting surplus ammo, along with one pistol. I bring a spray bottle of water to the range, flush the bores thoroughly before loading the car, and then flush them with water again at home before brushing with Hoppes, wiping clear with patches, and then smearing a film of oil up and down the bore. STILL got pitting.
I still have most of a tin of 54R left and a bunch of old 8mm ammo. I've got some bore polish on the way and I'm gonna hit everything with a brush and a power drill to knock all the rust crud out and hopefully stop further progression. I thought I was being pretty thorough on my prevention but apparently not. How do I stop dealing with this? Do I just have to trash all my surplus ammo and cough up for new ammo? How do all these other people shoot corrosive ammo all day long and not ruin their guns?
