Lots of youtube advertising videos, oops I mean reviews. With guys standing at a bench talking about a rifle they don't shoot on the videos .... no .458 Win Mag yet.

BTW when they work one of these rifles with a big scope on it, how aweful the sight picture must be and totally lost. Even with a red dot sight, getting the sight picture back must be slow and annoying.
