Jacket hardness/thickness

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...

Extruder Barrel n (extruder cylinder) A thick-walled, cylindrical steel tube, lined with a special hard alloy to resist wear that forms the housing for the extruder screw and contains, between itself and the screw, the plastic material as it is conveyed from feed hopper to die. Barrels are usually surrounded by heating and cooling media, such as electrical heater bands, cast-in-aluminum calrods and tubing for coolant, induction heaters, or, rarely, by a compartmented jacket for the...
