, or .38 SC. The .38 Long Colt is also known as .38 LC. The .38 SC and LC differ in case length and in bullet diameter, weight and design.

Design and Ballistics

The .38 Long Colt's predecessor, the .38 Short Colt, used a heeled bullet

. The cylindrical "shank" or "bearing surface" of the bullet, just in front of the cartridge case mouth, is .374 or .375 inches (9.50 or 9.52 mm) in diameter, the same as the cartridge case (exactly like the .22 rimfire cartridges). A smaller-diameter portion of the bullet, the "heel," is crimped inside the case mouth, and the lubricant is outside the case, and exposed.

In contrast, the .38 Long Colt uses a .357–.358-inch bullet, the bearing surface and lubricant of which are entirely contained within the cartridge case. This keeps the waxy lubricant from collecting grit which can damage the revolver's barrel. Unfortunately Colt retained the single-diameter charge hole, so the bullet was grossly undersize as it traveled through the chamber throat. It was supposed to expand in the throat and be "swaged down," or reduced again in diameter, as it entered the barrel, but expanded unevenly producing poor accuracy. Velocity was the same 770 ft/s (235 m/s), but bullets weighed 150 gr, resulting in a muzzle energy of 198 ft.lbf.

s at extremely close ranges. A typical instance occurred in 1905 and was later recounted by Col. Louis A. LaGarde:
"Antonio Caspi, a prisoner on the island of Samar, P.I. attempted escape on Oct. 26, 1905. He was shot four times at close range in a hand-to-hand encounter by a .38 Colt's revolver loaded with U.S. Army regulation ammunition. He was finally stunned by a blow on the forehead from the butt end of a Springfield carbine."


Col. LaGarde noted Caspi's wounds were fairly well-placed: three .38 bullets entered the chest, perforating the lungs. One passed through the body, one lodged near the back and the other lodged in subcutaneous tissue. The fourth round went though the right hand and exited through the forearm.

As an emergency response to the round's unexpectedly dismal performance, the U.S. Army authorized officers to carry the M1873 .45 Colt Colt Single Action Army
