I have had a bullet in my collection for a few years that when I bought it was identified as a bullet for a Burnside carbine cartridge (M&M #71, T&T #90A). A week ago I purchased a bullet which was identified as a bullet for a Sharps & Hankin carbine cartridge (M&M #72, T&T #125). I am beginning to wonder if both are not Burnside bullets. Bullet "A", the one identified as the Burnside, has a Diameter of 0.565 inches and a Length of 0,807 inches and weights 24.4 grams/376.5 grains. (Attached are a side and bottom view, labeled P9260153-1 and P9260155-1) Bullet "B", the one identified as the Sharps and Hankins, has a Diameter of 0.512 inches and a Length of 0.820 inches and weights 25.1 grams/387.34 grains. ( Attached are a side and bottom view, labeled P9260160-1 and P9260161-1) Under a magnifying glass, Bullet "B" show signs of being compressed as if it had been fired (?). So, what are your thoughts? Both Burnside or both Sharps and Hankin or one of each (and which one is which)? Thanks in advance! (P.S. Sorry I couldn't attach the bottom view of Bullet "B")
