From Wikipedia:
"The Mark 7 (Mark VII) used a 174-grain (11.3g) pointed bullet with a flat-base which gave a muzzle velocity of 2,440ft/s (740m/s).[2] The Mark 7 was different from earlier .303 bullet designs or spitzer projectiles in general. Although the Mark 7 round looks like a conventional fully-metal jacketed bullet, this appearance is deceptive: its designers deliberately made the front third of the interior of the Mark 7 bullet out of aluminium or wood pulp, instead of lead. This shifted the centre of gravity of the bullet towards the rear, making it tail heavy. Although the bullet was stable in flight due to the gyroscopic forces imposed on it by the rifling of the barrel, it behaved very differently upon hitting the target. As soon as the bullet hit the target and decelerated, its heavier lead base caused it to yaw violently and deform, thereby inflicting more severe gunshot wounds than a standard spitzer design."
Sorry about the little thread hijacking, but I just find the different types of bullets used, to be interesting. And I was reading about this bullet just a couple days ago, so this article sprung to mind.
