I was by cabelas the other day and saw a roa lee 456-220-1r mold for $20. I just started casting with round ball molds and decided to try conical bullets. I have about 150 cast up, ready for the range next week. I have t7 fffg, pyrodex P powder, sorry black is not available in this local, and lubed felt wads. I have no interest in light loads for these, I have rb for that. What would be the max load for t7 fffg and pyrodex P for the 220 grain conical? I do plan to knock back the max load by 15% as a starting load and increase from there.
