It didn't require steel wool, it just made the job faster. A green scrubby has done the same job. The stainless steel sink didn't rust just because it was touched by something rusty for 2 days. And it definitely doesn't rust just by holding water for 2 days.
You're now just twisting this into irrelevant bullshit. Have a nice day.
A collector generally only collects guns, not ammo. You don't need a million rounds for guns that are too valuable to actually use.
