Got the Lyman Great Plains Hunter .54 Cal out today, The last time i shot this rifle it was with fairly hard lead (9 to 9.5BHN) the rifle grouped well but was way to the right, i had to adjust my Lyman 57 way to the left in order to get zero, it was WAY off from the center of the Tang, Today i tried a different bullet, the Lyman Plains and they were poured from real soft plumbers lead, these bullets weigh 460 grains, i tried a fairly stout load, 95 weight grains of Swiss 2F Powder, and a .060 thou Vegetable Fibre over powder wad. The rifle shot EXTREMELY well!! 3 shots under an inch at 50 yards.
