This is not new. Back in the 70’s I did a lot of competitive shooting with a muzzleloader.
One of the novelty shoots was like this. You would shoot at an axe head with a clay pigeon hung on each side. And we didn’t have the gun clamped in a vise. We shot offhand at 25 yards.
It’s new from the standpoint of people investing serious money, time, and ingenuity to film and dissect some very interesting stunts. I’ve seen some of their other videos and they’re very entertaining. And given the number of views their videos have, I presume there making some serious money doing it. I applaud them.
