High Desert Cartridge Company .38 Special 148 Grain HBWCs

 Today I ran some High Desert Cartridge Company .38 Special 148 grain HBWCs over my Garmin chronograph from 2 .357 Magnum revolvers.

First, from my S&W 640-1 with a 1-/7/8" (nominal 2") barrel, 10 shots averaged 753 FPS.



Second, from my S&W 66-2 with a 2.5" barrel, 8 shots averaged 788.7 FPS. For some reason 2 shots didn't register.



Everything else being equal, I would expect 25 - 50 FPS more velocity from a gun chambered in .38 Special, due to less freebore.

High Desert Cartridge Company advertises this load at 725 FPS from a 2" snubbie with 18" of penetration in ballistic gelatin.

In my opinion this would be an excellent carry load in .38 Special of .357 Magnum snubbie revolvers. It's controllable in rapid fire but will poke a clean hole all the way into the vitals.
