Going to pick up some Hornady 105g HPBTs to try from the 24" barreled 10" twist 240 WBY vanguard. Anyone have any experience with the 105s in a 240 WBY? I have most of the H4831 and slower powders on hand. Thinking maybe RL26 would be a good one for velocity. Any ideas on where to start and what velocity should be like? Thanks.
