That's a proper air rifle, not some /toy/ shit like the OP is talking about.
The high end air rifles are neat, but the lower end ones aren't really any bad either. The velocity difference can be quite marginal.
I saw a video of an American killing wild pigs with a .22 air rifle. He shot them in the ear and the slug went through the back of the brain, killing them instantly. Something that I think could totally be possible with a .177.
Estonia has a very dumb law where only .177 air rifles are allowed. Checking around online stores, air rifles that get ~1000fps are not that expensive. Apparently the .177 model of that thing in your video can get 1450fps.
