So I just bought a 6.5/300;Weatherby a few weeks ago, the problem is there very little reloading data. Loadata has 4 loads using 7828 with 110gr, Realoader 50 and US 869 with a 130gr, and Reloader 50 with a 140gr. I have US 869 and 50 BMG my plan is to use a 140gr Accubond, I’ll try 869 by dropping the load and starting from and work up. Does anyone have other loading data or has used a different powder, thanks in advance.
