Low-Pressure .45 Auto Rim Ammo for Shaved Cylinder Webley Revolvers
Steinel’s .45 Auto Rim Ammo Low Pressure 185gr SWC load was specifically developed for shooters using shaved-cylinder .455 Webley revolvers who want reliable function without the need for moon clips. Carefully engineered around lower operating pressures and traditional revolver shooting characteristics, this load provides dependable performance while remaining appropriate for historic revolver platforms.
Loaded with a 185-grain cast and coated Semi-Wadcutter projectile sized to .453″, this cartridge produces approximately 650 FPS from 6-inch Webley revolvers while operating at approximately 12,000 PSI. The result is a smooth-shooting, mild-recoil load designed to complement vintage British revolvers converted to accept .45 Auto Rim cartridges.
