Astounding nonsense.
I know it's not nice for me to say so but, hey, you are calling me an idiot.
I shoot off hand ("free hand", in the video) 3-4 times a week with CF rifles at 100 yards. In this season I shoot a 7" x 9" steel plate.

This is from one of my last outings. The cartridge is 2.25 inches long so I guess that puts pretty close to a 4" , five shot group. This was from a Ruger bolt action but I most often shoot my Tikka 308 T3 as practice for my identical 7mm-08. Four inches is not that difficult if you practice.

Tikka 308, off hand (on a very good day) witnessed by a SD Member, btw.

Again. Tikka 308 off hand on an average day. All 100 yards, standing.
So don't give me that crap about it can't be done. To hunt in my country you better be able to shoot off your own hind legs or stay in the truck and wait for the hunters to come back. ~Muir
