After many customer requests, Buffalo Bore is proud to introduce two powerful +P .45 Auto Rim loads. Both loads are built with premium Starline brass and feature flash-suppressed powder to preserve shooter vision in low-light conditions—a critical consideration, as over 95% of civilian shootings in the U.S. occur in the dark when threats are most active.
These loads match the ballistic performance of +P+ .45 ACP (also known as .45 Super) but operate safely within the limits of modern and post-war .45 ACP revolvers in good working condition.
Real-world velocity tests were conducted using personal revolvers—not laboratory barrels. Notably, the newer S&W 4-inch Mountain Gun delivered speeds nearly equal to older models with longer barrels, demonstrating the tighter tolerances of modern S&W revolvers.
Item #32B – 200gr Jacketed Hollow Point:
- 1,197 fps – S&W Mountain Gun, 4-inch barrel
- 1,080 fps – S&W Model 325 (Scandium), 2.5-inch barrel
- 1,203 fps – S&W Model 1917 (1937 production), 5.5-inch barrel
- 1,249 fps – S&W 1955 Target (25-2), 6.5-inch barrel
Item #32B is engineered for expansion and significant terminal damage. It offers less than half the penetration of Item #32A, with an expected depth of approximately 14 inches in live tissue and bone.
