Rifling, the addition of spiral grooves inside a gun barrel, imparts a stabilizing spin to a projectile for better external ballistics, greatly increasing the effective range and accuracy of the gun. Before the introduction of the Minié ball, balls had to be rammed down the barrel, sometimes with a mallet, because gunpowder residue would foul a rifled bore after a relatively small number of shots, requiring frequent cleaning of the gun. [3] The development of the Minié ball was significant because it was the first projectile type that could be made with a loose enough fit to easily slide down the barrel of a rifled long gun, yet maintain good accuracy during firing due to obturation by expansion of the bullet's base when fired.

Despite their petiteness, bullet vibrators offer powerful pleasure. “Because the surface area is small, especially at the tip, these toys will seem pretty intense to many users when they touch their clitoris or other sensitive bits,” Queen says. She recommends wrapping a bullet in a soft fabric to help spread the sensation out even further.Leavitt, T. L. (2 September 1865). "Tenacity of human life as seen in cases of gunshot injuries". Medical and Surgical Reporter. 8 (10): 151–152. When the Crimean War erupted between Russia on one side and the British and French on the other, the two western European nations demonstrated the effectiveness of their new weapons against the Russians’ smoothbore muskets. The London Times called the Minié “the king of weapons” that swept through the ranks of the czar’s soldiers “like the hand of the Destroying Angel.” The Minié ball in the American Civil War

Captain James H. Burton, an armorer at the Harpers Ferry Armory, developed a major improvement on Minié's design when he added a deep conical cavity at the base of the ball, [ clarification needed] which more efficiently filled up with gas and expanded the bullet's skirt upon firing. A higher percentage of the explosive force went toward forward projectile motion and lesser percentage toward fitting into the rifling. Burton's modified Minie ball had decreased mass and increased speed, resulting in increased energy and better range, as well as a cheaper bullet, which was used in the Crimean War [ citation needed] and then the American Civil War. [3] Burton's version of the ball weighed 1.14 ounces.

What are the benefits of a bullet vibrator? Every bullet was tried by at least five people for several weeks, with every setting, claim and innovative feature put through its paces.The Minié ball, or Minie ball, is a type of bullet used extensively in the American Civil War. The muzzle-loading rifle bullet was named after its codeveloper, Claude-Étienne Minié. In the 1830s, Captain John Norton of the British 34th Regiment was serving in India. Some local tribes used blowguns, and Norton observed the base of their darts was made from pith, the spongy wood from the center of tree trunks. This pith expanded when a person blew into the blowgun’s tube, closing the space between the tube and the dart to give a tight seal that increased the dart’s range.
