SAAMI and C.I.P. measure pressure differently and their figures are not interchangeable, which is why the body is always named beside the figure.
Loads
Velocity is recorded per barrel length as published. A gun page interpolates between these points and never projects beyond them.
98 gr LHBWC
- Bullet mass
- 6.35 g98.00 grestimated
98 gr bullet, from a handloading data page (Hodgdon), via the Wikipedia infobox. The published velocity on that page is a maximum-handload result tied to a specific powder charge, not a factory-ammunition figure, so it is not recorded.

Detail
The .32 S&W Long is a rimmed, straight-walled revolver cartridge Smith & Wesson introduced in 1896 by lengthening its own earlier .32 S&W case. Colt chambered the same round in its own revolvers under the name .32 Colt New Police, and both names describe the identical cartridge rather than two different rounds.
The round was widely chambered in small- and medium-frame pocket and police revolvers from both makers through the first half of the twentieth century, valued for its light recoil compared to larger service revolver cartridges of the period. It remained in production for target shooting and small-frame defensive revolvers, and its case later formed the basis for the longer, higher- pressure .32 H&R Magnum.
All dimensional and pressure figures on this page come from C.I.P.’s published standard and are recorded as verified. Three bullet weights are recorded from a handloading data page cited by Wikipedia’s infobox, but that page’s published velocities are maximum-handload results tied to a specific powder charge rather than factory-ammunition figures, so no velocity or energy is recorded for this cartridge. No photograph of a revolver chambered for it appears on this site.
