That Russian stuff was probably corrosive primers, yes? But the USGI .45, not? Just curious, I have a rough idea what is likely corrosive, and what isn’t, but haven’t been around much that was that old to be worried about it.
I don’t have to worry about the coolers, I have enough space in my climate controlled basement.
Corrosive primers just means you clean the barrel with boiling water and/or military cleaning solvent after use.
Not hard to do with a .45 1911A1.
