In some cases, interlocks can be purely mechanical, such as in firearms internal safety, preventing firing pin release if the chamber is not closed properly. | United States of America. When a hunting bullet impacts a broadside game animal in the crease behind the shoulder and slips between ribs: Depending on nose design, the tip of the bullet mashes rearward, forcing the soft lead core behind it to expand, bulge outward and flow out and rearward, creating a mushroom shape. The tip also acts as a method of initiating expansion and increases the ballistic coefficient of the projectile. A solid bullet from the outside (left) and inside (right). They were very expansive even at those relatively modest velocities, I had several with complete core separation and failure to go through and through. The combination of the slender point and increased bearing surface results in lower drag, increased stability, flatter trajectories, and amazing accuracy. Also Know,how do you use interlock?
