It's been quite a while since I have used that load I really don't remember the charge. I do remember that I was shooting Elephant brand FFg, but the exact charge that worked the best, I really can't remember. The REALs were finger lubed with Bore Butter and I think the cap was CCI regular.
However I do remember a 50 yard three shot group that all were touching with that combination. Just start with the suggested load that comes with the mould and then adjust for accuracy from there. Everyone's barrel is a bit different and you just have to try till you find the combinations that yours likes. Just like barrels, each lot of blackpowder is also a tad different and it's just experimentation.
