Buffalo Bore makes a "Standard Pressure Short Barrel Low Flash HVY 38 Spl (non+P)" round, loaded with 125 grain Speer "Low Vel." JHC, rated @900 fps muzzle velocity, for non+P rated snub nosed revolvers. However, they don't shoot to the point of aim for me. My Cobra (circa 1968) seems to have been regulated to be used with 158 grain projectiles. Accordingly, I load my Cobra with Hornady "Custom", 158 grain JHP/XTP, non+P ammunition, rated @ 800 fps muzzle velocity. POI/POA with this ammo shoots a little high @ 25 yards but is pretty close @ 15 yards. It's pretty controllable for a revolver weighing in at 16 ounces.
