I hunt in saltwater and this is really corrosive on shells the "brass" on them will begin to rust after only a few hours if exposed to the elements.
By using this tool you can clean and protect your shells in a few seconds, the tool has a tapered hole that will securely hold 10 gauge or 12 gauge cases. The tool is used by mounting on a 1/4" drive in an electric screwdriver or drill, i put a drop or 2 of oil on a scotchbright dishwashing pad and grip the brass section of the shell and give it a spin or 2 this will clean or remove any rust and leaves your shell with a light coating of oil to help protect it in the future.
