Ok, I was wrong.
As to the "gem", sure it does:
Non-Expanding Bullets
Non-expanding (FMJ) bullets typically retain their general shape as the bullet penetrates and passes through target. The penetration of this type of bullet is usually much greater than frangible or expanding bullets because the frontal area of a non-expanding bullet does not increase as it penetrates.
In round nose form they are favored by some African hunters for use on the largest and toughest game, principally on elephant and rhino, where very deep penetration against heavy hide and bone is required.
But there are two kinds of solids, monometals like Barnes solids and FMJs (with lead cores) like Woodleighs, etc.
