One Cartridge, Not a Box: .50 Cal Spotter-Tracer, M48A1 made from shortened  .50 BMG Lake City cases for the smaller Rifle mounted on top of the 106mm recoil-less (BAT) for (Battalion Anti-Tank) Artillery Cannon.  The projectile has a primer at the tip to ignite a mixture that produces a smoke spotter on impact, and also a tracer cup in the rear of the projectile to produce a tracer out to 1500 yards.  The projectile matches the trajectory of the 106mm cannon projectile to follow, to ensure the 106mm has a good target impact.

Also known as the 12.7x99mm in Europe, has been used extensively in almost every U.S.A. conflict since its adoption in 1923.Adopted by the U.S. Military in 1923 the .50 BMG has been used longer than any other cartridge in military history. (Note:  The .45 ACP is actually older, but was technically superseded.) Technically the .50 BMG is the biggest cartridge available  to shooters without encumbrance legal restrictions. (There are other wider diameter cartridges, but none larger available)
