I have no idea how many rifles Boone may have owned over the years, but I suspect it was more than one. The fact that one of them may have survived to the present day is pretty remarkable. Boone himself once stated that the rifle he used to kill Pompey, the renegade African-American who was besieging Boonesboro along with a band of Indians "carried a one-ounce ball", making it a 16 ga., or about 66 caliber. A pretty large bore for a Pennsylvania rifle, but not unheard of! He did not say if HE owned this rifle..... obviously not the one described above, however! Boone said the shot was made at a distance of about 150 yards, the shot striking Pompey, who was in a tree sniping at Boornesboro at the time, in the center of his forehead...... Good shot, Dan!!
