Your first bullet is a copper-jacketed .45-caliber ACP (Automatic Colt Pistol) bullet... manufactured continuously from 1911 through the present. I should mention, also used in the .45 Thompson Submachine Gun ("Tommy Gun").
Second bullet is a .38-caliber "semi-wadcutter" bullet, manufactured from the mid-1900s through the present. Wadcutter bullets are primarily made for target shooting, because the bullet's wide flat top punches a clearly visible neatly round hole in the paper (or wooden) target.
