Spent a lengthy amount of time developing loads for my 475 Linebaugh using Accurate 11 FS powder.

Love the accuracy potential of the powder but it?s one of the dirtiest powders I?ve ever used.

Cases come out filthy. After first 5 rounds in my clean BFR, I had trouble getting next 5 to load without pushing them into the chamber.

11 FS was a military powder that was chemically designed to reduce muzzle flash by 90 percent.

Maybe it has better application in rifle cartridges but definitely not pistol or revolver.
