It's called Jim Shockey's Gold FFG
In the Feb issue of the American Rifleman they tested this black powder substitute. The mfg claims to have fired 5,562 shots over a 90-day period without ever cleaning the bore. I would like another opinion on how well it works in a hunting situation when you need to get a second sabot down the barrel for a follow-up shot if needed. I will no longer use 777 because I can't get the sabot down tight on the powder for the second shot without swabbing the bore. (Not easy to do when you're in the tree stand)
