The .38 Short Colt, also known as .38 SC, is a heeled bullet cartridge intended for metallic cartridge conversions of the cap and ball Colt 1851 Navy Revolver from the American Civil War era.

[1] Later, this cartridge was fitted with a 0.358-inch (9.1 mm) diameter inside-lubricated bullet in the 125–135 grains (8.1–8.7 g) range.

[2][3] Visually, it resembles a .38 S&W but the case dimensions are slightly different.

Remington is one of the few producers of this cartridge today with a 125 gr LRN bullet.

Magtech produces this grain weight and Ten-x manufactures a 95 gr load, as well as blanks.
