You have to love Jim March. I hadn't read much of his stuff until recently, but he is both technically competent and tactically proficient.
He is the author of the Jim March Revolver test, which is good stuff to know if you ever buy a used revolver.
He also knows how to pimp-slap idiots, as he shows in this High Road thread.
From voter fraud, to historical accuracy, to revolver technical advise. Good stuff. Go read it all.
