I have pushed a couple loads through my Genesis. These were bullets loaded after shooting deer.

Aside from staining of thecopper jacket and very minor rifling marks, the bullets looked fine. I cleaned them up and have put one back in a speed loader, and the other is loaded in the gun right now.

That bullet was easy to start in the muzzle, I was able to press it in by hand. I believe it will shoot fine, it is in the same condition it was when it was first loaded.
