I thought he was older than 58. I need to go through his older videos. He has done a lot of past content that is a bit different than most. I recall he looked at how bullet proof a log cabin wall is. He also tested a lot of ammo that others didn't. A lot of others talked crap about his meat target, but it largely showed the same ranking that gel testing did.
He also did a bunch of shotgun content including 20 gage and 410 gage.
