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.
40 gr HP
- Bullet mass
- 2.59 g39.97 grestimated
40 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 .222 Remington is a rimless, bottlenecked rifle cartridge Remington introduced in 1950 as the first commercial rimless .22-caliber cartridge made in the United States. Its accuracy and flat trajectory led to its adoption for varmint and benchrest rifles.
In 1963 a stretched version of the .222 case, the .222 Remington Special, was standardised alongside the new M16 rifle as the .223 Remington and 5.56×45mm NATO; the .223 Remington and 5.56×45mm NATO entries on this site have the fuller account of that later, larger-scale military development. The original .222 Remington itself was never adopted as a military round and has remained a civilian sporting cartridge throughout its production life.
All dimensional and pressure figures on this page come from C.I.P.’s published standard and are recorded as verified. Four 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 rifle chambered for it appears on this site.
