A shotgun shell that cleans your bore? - Cleanshot tests

We test out some shotgun shells designed to clean the bore of your gun after you are done shooting. These are available at Walmart - I paid about $8 for a box of 4, while others have told me these are cheaper at their local Walmarts. These are designed to clean your gun, but they still have around 1 oz of lead shot in them and all safe gun-handling practices must be obeyed. Do you think our tests were fair and honest? What did we do wrong? Your support on Patreon is greatly appreciated. You can use PAYPAL on Patreon, for your online security and convenience.   / taofledermaus
