Fired .45 ACP cases can be resized and trimmed to handload .400 Corbon cartridges. [20] New brass cases are manufactured by Starline Brass and are readily available directly from them and major mail order retailers. [21] According to Starline Brass, "The primer pocket was changed from large pistol primer to small pistol/rifle primer in 12/00.
An obturating ring which is called driving band made of a softer material is the standard solution for that problem. Mortar bombs also use obturating rings to provide a seal around the projectile. [ citation needed ] Recoilless rifles and some artillery use rings with a reverse impression of the rifling cut in them for a tighter seal even at ...
Renewed western interest in bottleneck handgun cartridges began with the .357 SIG in 1994 (necking a .40 S&W case down to a .355 bullet); followed by the .400 Corbon in 1996 (necking a .45 ACP case down to hold a .40 cal. bullet); and then the .25 NAA in 1999 (necking a .32 ACP case down to hold a .25 caliber bullet). 2015 saw the introduction ...
Using this cartridge at full power in a handgun built around the standard .38 Super +P pressure limits and lower may result in a drastically increased level of wear on the firearm or even serious damage to it due to insufficient tensile strength and hardening of the frame, slide and various small parts. This is not a significant design problem ...

The 9×21mm pistol cartridge (also known as the 9×21mm GP, 9×21mm IMI, 9mm IMI, 9×21mm Italian, or 9mm Italian) was designed by Jager (Loano, Italy), then adopted and commercialised by Israel Military Industries for those jurisdictions where military service cartridges, like the 9×19mm Parabellum, are or were illegal for civilian purchase (i.e. Italy, France, Brazil, and Mexico).
Driving bands and obturator rings are made from material that will deform and seal the barrel as the projectile is forced from the chamber into the barrel. Sabots use driving bands and obturators, because the same manufacturing tolerance issues exist when sealing the saboted projectile in the barrel, but the sabot itself is a more substantial ...
