After learning to reload and seeing the dangers of not knowing what can happen when using wrong loads or powders, I have a very healthy respect for things that go BOOM!!
The best thing you did was use the Silvadine. I always have Colloidal Silver on hand at my house. Don't use any alcohol or hydrogen peroxide after the initial cleaning of the wound, like say later that day or the next day because it kills the skin and any new skin trying to heal/grow. Colloidal silver has saved me many times from things getting infected!!! And the wounds always heal nice after using it.
