Remember reading in old Shooting & Fishing magazines that "back in the day", folks loaded round balls in cartridges for single shot rifles. Now that I have this 450 Nitro #2 and only access to an indoor 25 yard range (until June), I've been thinking of trying some. As I recall, in the 45-70 they used a .458 round ball with a light load of Unique, topped by cornmeal with a waxed fabric wad under the bullet and a light crimp to retain the ball.
Thinking that the 44/45 TC bore butter button patches under the ball would work well and substitute dacron for the cornmeal and trail boss for Unique. Thoughts ?
