Most people have a hard time being realistic. Everyone wants to be perceived as being better than average, so people embellish. Sometimes for so long that those embellishments become "their" truths. Then when a guy like this comes along and tries to be realistic on a platform (Youtube) that survives on highlighting the above average, people call him a goof.
Case in point, I know a guy that has an X95. Claimed it will shoot 1" groups at 100m with factory ammo. I told him I would give him ANY amount of money if he could sit down and shoot 2 or 3 5-round 1" groups at 100m. To his credit, he actually attempted it with us present, but it was nowhere close. Best group he got was about 2 1/4", which I was still reasonably impressed with to be honest, as Tavors aren't known to be super accurate. But I think he fluked a single MOA group one time, and assumed he had a 1 MOA rifle.
...But for real though, what kind of weirdo names their kid Ruger?
Knew a guy who named his dog Ruger once. - dan
