Laser-guided and high-velocity?

I wouldn't think that alcohol (and who knows what else), high altitudes and firearms are best when combined. Apparently I am wrong. From Hitch's obit of Hunter Thompson:

And there, at the very fringe of habitation, was Owl Farm and its genial proprietor, Dr. Hunter S. Thompson. Once inside these well-armed precincts, I could drink and smoke and ingest any damn thing I liked. I finished a fairly long evening by doing some friendly target-practice, with laser-guided high-velocity rifles, in the company of my host.

I get the feeling that Hitch knows or knew everyone.
