The heeled bullet design has many advantages, mainly when coupled with the straight or slightly tapered walled cases it appeared in. For pistols, converting a cap and ball revolver to use cartridges was as simple as cutting off part of the rear of the cylinder, replacing it with a frame-mounted ring, and changing the hammer. It also made new ...
The barrel was about 0.404–0.406" groove diameter. The bullet lubrication was outside the case. At 0.386–0.388" OD, The base of the bullet was smaller in diameter to fit inside the case. This is known as a "heel-base" or heeled bullet. The only modern heeled bullet is the .22 rimfire. In the mid-1890s, Colt redesigned the cartridge.
The original .44 Colt loading used a heeled, outside lubricated bullet. The major diameter of the bullet was approximately the groove diameter (.451 in) of the converted ".44" cap and ball revolver. The smaller "heel" at the base of the bullet was sized to fit inside the brass case at approximately .430 in. [2]
The .44 Remington Centerfire / 11.4x27mmR (often referred to as .44 Remington C.F. or .44 Remington) was a centerfire revolver cartridge with a heeled, externally lubricated bullet produced by the Remington Arms Company from 1875 until 1895.
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.

A smaller-diameter portion of the bullet, the "heel", was crimped inside the case mouth, and the lubricant was outside the case, and exposed. [a] In contrast, the .38 Long Colt uses a bullet which on the outside of the cartridge case is only .357–.358 in (9.07–9.09 mm), the bearing surface and lubricant being entirely contained within the case.
As Webley had used the .38 S&W cartridge dimensions for their revolver, and the cartridge length was fixed by the size of the cylinder of the revolver (the same as for the wider .455), Kynoch produced a cartridge with the same dimensions as the .38 S&W but with 2.8 grains (0.18 g) of "Neonite" nitrocellulose powder and a 200 grain (13.0 g ...
