I am going to work up a load for a custom rifle chambered in .300 Weatherby Magnum. This will be a long range Elk load. My bullet choice will be either a 200 grain Nosler Accubond with a .588 BC or a 210 grain Berger with a .631 BC. I will be using either Retumbo, MRP, RL22 or RL25 powder with Weatherby cases and Federal 215 primers. I know how the Accubond expands on large game but have no experience with the Berger. I would appreciate your input and pet load using theses components.
