"The only way to test for that is firing it without a bullet, rifle primer, plastic sabot, swabbing liquid, gun oil or humidity present - then letting the gun sit for a long time in an opened air environment."
Those are novel suggestions for the experiment. Do you believe a plastic sabot or a lead bullet, or primer to be corrosive? I don't understand your point.
My experiment was conducted with a cap and ball pistol. I fired one cylinder.
Thank God, I ran a patch down the bore of my expensive pistol after firing. I did not clean the cylinder or the hammer.
I let the pistol set for 4 weeks in a drawer before I checked up on it. I had meant the experiment to go only for a week. Good plan, bad implementation. This was in the mountains of North Carolina, high humidity.
When I checked my Uberti, the cylinder was covered with red rust, as was the hammer.
I spent three hours cleaning my poor pistol up. It did clean up ok and works fine now.
No more expensive, scarce MagKor stuff for me.
By the way, I liked the performance of BlackMag3. It had a little more power than black powder. It was easier to clean up than bp.
