The second or third die in the set seats the bullet and may apply a crimp. A fourth die is often used to apply crimps after the bullet is seated. [13] Sometimes an additional "die" is used to mount powder measures which makes dispensing powder into the case a part of the process. This die usually flares the case mouth to allow easier bullet ...
Used in single-shot firearms (e.g., Thompson Center Contender or Encore), no crimping is absolutely required, but higher velocities may be achieved with either a roll or taper crimp, depending on cartridge, to permit pressure to rise higher before the bullet is released from the brass case.

Whether a 300 BLK cartridge actually is able to chamber in a .223 barrel depends on bullet length and shape, bullet seating depth, crimping, and the volume of powder charge. Ideally, cartridges would use one of the longer projectiles, a case-filling powder charge, and have the projectile crimped into place.

For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
“Very small,” she said, pointing to the slug, “like a .22.” As so many other patients do, the patient asked the trauma surgeons if they were going to take the bullet out, and the surgeons explained that they fix what the bullet injures, they don’t fix the bullet. They left the wound open to prevent infection and put a dressing on it.
Rock Chuck Bullet Swage (later abbreviated RCBS) is a handloading equipment manufacturer operating in Oroville, California. The company originated during the sporting ammunition shortage caused by World War II , became a widely recognized manufacturer of handloading equipment, and has subsequently been purchased by Hodgdon Powder Company .
Individuals who make their own bullets usually are not aware of available manual specialized equipment and dies required for swaging bullets, [citation needed] and thus choose to make cast bullets. To get high precision results, it is common to cast the bullets slightly oversized, then swage the resulting castings through a die to do the final ...
