Cartridges

My printer is very low on all four ink cartridges, and the quality of the printing is poor.

"Have you any arms?" "I have my old service revolver and a few cartridges."

I have always held, too, that pistol practice should be distinctly an open-air pastime; and when Holmes, in one of his queer humours, would sit in an arm-chair with his hair-trigger and a hundred Boxer cartridges, and proceed to adorn the opposite wall with a patriotic V. R. done in bullet-pocks, I felt strongly that neither the atmosphere nor the appearance of our room was improved by it.

The cartridges are easy to refill.

The term "ballistics" refers to the study of a projectile in motion. Ballistics also refers to the forensic study of bullets, cartridges and firearms in criminal investigations. When a bullet travels through a gun barrel, the bullet's metal gets worn in a unique pattern by the harder metal of the barrel. Unless there has been some intentional alteration, any bullet fired by a specific gun will show the same marks.
