Bringing this back to life since I just acquired a 257 Wby Vangurad Sub-MOA (this is a Vanguard I model not the newer Vanguard II).....any one using any of the newer powders RL 23 or RL 26? Maybe IMR 7977? I do have some H 1000 on hand but will need to buy some powders to experimwent with. I plan to force feed it 100 gr TTSX bullets and if it refuses plan to try 110 Accubombs and 120 A-frames.
