Goex "5fa" works great and is very accurate for all range work, woods-walk, and plinking applications. It's an unglazed mix of 2, 3,and 4f powder. I think the 4ffff part really improves its ignition performance in a flintlock, way more reliable than Swiss 3fffg.
Not sure what products are re-packaged as Reenactor, but probably bulk 5fa is one of them.
Only occasion to use my Olde Eynsford/Swiss is when I am hunting elk,..Velocity (recoil) gain is significant with Eynsford and Swiss,.. though it's only worth it for hunting.
