Berger makes target, varmint, hunting, and tactical bullets, all to match standards. The ones I was shooting were the second category, called Hunting VLD (for Very Low Drag), .308, 155-grain. VLDs are made with J4 copper jackets, lead cores, very small hollow points, a very long secant ogive, and a pronounced boattail base. They come in 6mm through .308. What I can tell you also is that they are exceedingly aerodynamic. The wind can't seem to grab them, and they drop far less than the numbers say they should. Every time I estimated how much to hold over at long range, they hit higher than I guessed.
