He brought a great deal of useful, no-BS firearms content to YouTube media, without the false bravado, obnoxious narcissism and smug shilling that 90% of the functional idiots on that medium deliver.
He was an accomplished shooter, a military veteran, and a humble sincere educator. His dry wit, and flair for creating interest out of what could be mundane content, also made him popular, while presenting a wide range of firearms topics from a position of knowledge and sincerity. Pioneering and perfecting his signature "meat target", he provided a unique perspective on bullet performance.
Along with all that, he made entertaining non-firearms content, like his Thanksgiving Day specials, and outdoor cooking demonstrations.
I hope his content stays online, as someone looking to learn could not do better than start with his videos.
