Just found one of my old photos of a bullet I cut in half; its interesting to see just how much aluminum is at the front of the bullet and holding the lead very much to the rear and making that rearward center of gravity the ol 303 is known for.

The other standout feature is the varying wall thickness on each side of the lead, no wonder there's all sorts of discussion about varying quality of war time ammo, and the corkscrew flight this feature will cause when the rifling gets it going at 174,000 rpm.
