I have done a ton of research on this, and have come up with little to nothing. Does anyone know where a good starting load would be for this? Or n570. Im looking for a starting powder charge (which I will probably start lower than you tell me) and a starting seating depth. It’s on a weatherby vanguard backcountry. There is little to no data for any of the heavies with the 6.5-300. Any help is appreciated fellas!
