Being in the broadcast news business I've seen this report.
I think it is one of those things that gives hunting and hunters a bad rep.

He apparently only has it shooting at a target with a Marlin .22.

There are some serious issues about hunting and killing game in the State of Texas without a license.
If you shoot a rifle in Texas at game you have to first pass or be exempt on a hunter/firearms safety course.
You need a license, resident/nonresident. . . tag the animal if it's a deer. . .etc.

Just my own opine here, but this guy is just BS and so is his scam!
