This video tests Flex Seal liquid rubber as a DIY shotgun slug, demonstrating its failure and danger. The custom slugs showed erratic accuracy and a significant ricochet risk when fired from a GForce Arms 12-gauge shotgun into ballistic gel. The host strongly advises against using Flex Seal for ammunition due to unpredictable and hazardous performance.
