4.7 grains of trail boss under a 180 grain grandmaster lead SWC. Very light recoil, super accurate, virtually zero leading. Surprising little smoke despite lubed lead bullet. Nearly full case of powder, but not compressed as I pulled a couple to ensure I wasn't crush'n the donuts... I shot about 100 of these this weekend and will be making a bunch more!
