Trail boss IS the easy answer. However, some don’t care for the slight extra cost, and it might not shoot well in your gun. I’ve used it in .38/.357, .44 mag rifle, and .45 Colt with total satisfaction, and even some rifle loads with more mixed results..
It’s very fluffy stuff, and a sneeze will scatter it hither and yon. My Little Dandy didn’t work well with it either. I might just try dipping it next time.
DO NOT compress it.
