Bullet jacket designs

There is also a wide variety of bullet core/bullet jacket designs without even considering compositional differences. Bullets are unjacketed, or... 

AP rifle bullets usually have a bullet tip filler (usually lead) which is designed to cushion the effect of the impact on the AP core, which is very hard and brittle and can break on impact without a cushioning effect. The AP core is also frequently surrounded with a thin sheath of lead between the core and the bullet jacket. The AP core is usually hardened steel such as tungsten/carbon, tungsten/chromium, manganese/molybdenum, chro-mium/vanadium, or chromium/molybdenum. 

Originals - Copper jacketed and cannelured, Originals have a soft lead interior. These heavy-for-caliber bullets are designed for penetration without fragmentation for rifles or handguns.

The vast majority of modern bullet types is either completely or partially jacketed, usually with gilding metal, and is produced in a range of shapes, sizes, weights, and designs depending on their intended use. 

The thickness and hardness of the jacket can vary between the base and the nose of the bullet, with the nose portion thinner for better expansion on impact or thicker for greater penetration of the target. The way the jacket is physically attached to the core can vary. This depends on the desired effect of the bullet on the target, either the controlled expansion of the bullet, greater penetration of the bullet, or the prevention of core and jacket separation. Figure 11.3 illustrates some different physical designs.66... 

KTW bullet The original design had a hard steel or tungsten steel core with a copper gas check and the current version is a solid brass or bronze bullet without a gas check. Both have a gliding metal half jacket and the exposed portion of the bullet is coated with green-colored Teflon. 

Another German design was a jacketed bullet with a hollow in the nose. On impact the steel plug squashed the glass ampoule against the lead core, causing the fluid to pour out of the nose cavity. This is illustrated in Figure 11.13. 

Type III flexible armonr shall be tested in both the as new state and the conditioned state with 7.62 mm FMJ, steel jacketed bullets (US Military designation M80) with a specified mass of 9.6 g (147 gr), and a velocity of 847m/s 9.1 m/s (2780ft/s 30ft/s). 

The X-bullet was quickly followed by Barnes Burners, jacketed rifle and handgun bullets designed for target-grade accuracy and varmint shooting. 

Bullet performance drives Barnes designs. Whether a Barnes bullet contains a lead core or not depends on the desired terminal performance. We have several lines of products manufactured from lead-free materials that were developed for their performance. These happen to meet the criteria set forth under the Condor Preservation Act, but we still manufacture the premium Original line of jacketed, lead-cored bullets. A lead ban would remove the very foundation on which our company was built. 

SinterFire bullets are full-bodied one-piece designs with no jacketing, plating or surface treatment. Materials are 100 percent certihed, fully traceable (by paper trail) and virgin, meaning there is no chance that extraneous recycled materials will be inside a bullet to reduce its performance. That way, Benini says, the company can control the fragmentation properties of the projectile upon impact with hard surfaces. Bullets literally crumble to dust on impact with surfaces harder than themselves. 

Speer loads Lawman Clean-Fire with Speer TMJ. The lead core is completely and seamlessly encased in jacket material so powder gases can t burn lead off the bullet base. This design is superior to other base cap bullets where the caps can loosen, leaking lead and destroying accuracy. 

CleanRange loads are designed to eliminate airborne lead and the need for lead retrieval at indoor ranges. CleanRange uses lead-free primers, but its lead core is copper jacketed for a fully encap-sulated bullet. This eliminates lead and heavy metal exposure...
