My first ML rifle (1970)was an original H&A underhammer in .36. It was the deluxe Heritage model with nice wood and a tang peep sight. Not knowing any better, a friend and I made a sorta conical mold from brass stock and cast our own bullets. With them the H&A would shoot 1" groups at 100 yds all day. It a fit of poverty I sold it off many years ago, but wish I still had it.
