I've probably had more luck with the 140-grain Berger Hunting VLD than any other.
In more conventional hunting bullets Barnes and Hornady are generally easy to work with, but I've also had great luck with the 140 Nosler Partition in cartridges from the 6.5x55 to 26 Nosler and 6.5-.300 Weatherby. Had a 6.5-06 for several years that I naturally tested LOTS of bullets in, to write articles for at least 3 magazines, and while the 140 Berger was most accurate, the 140 Partition was firmly in second place, not too far behind.
