Just for the record, all flatnosed bullets aren't wadcatter bullets, nor are the ones in question here. A wadcutter bullet is completely flat all the way across the diameter of the nose of the bullet. The bullets in question here are of what is commonly called a "Keith " style bullet, or semi-watcutter, and the flattened area on the nose is designed to create a larger wound cavity than on a regular round nose bullet. Also, some lever action rifles required a flattened nose on their bullets to prevent a "chain fire" in the tube magizine of the rifles. A sharp nosed bullet was found to move forward during recoil and hit the cartridge in front of it and cause it to fire in the magazine. Monty
