My dad used to shoot these. Kind of an innovative design for the time, using a lighter nose on the bullet (aluminum) moving the center of gravity back. The Aluminum nose also reduced bullet deformation in the magazine caused by recoil. Plus they looked cool. Ha! I know my dad and pretty sure a brother of mine killed some mule deer with these. I remember one recovered bullet from a deer that was mushroomed 'text book perfect'. 130 grain in 270 Win.
