G-man, that looks exactly like a mix-and-match batch of my general purpose .38 Special reloads. Mine are stoked with a bit more goodness in the form of 4.8 grains of Unique, giving 810 fps from a 2-inch barrel and 858 fps from a 4-inch barrel.
I buy into the notion of the lead wadcutters and semi-wadcutters for both field or personal defense use. I gotta say I prefer a bit more "starch" in 'em than is being indicated here. From 925 to 1000 feet per second velocities is my happy place for a hunting/personal defense load for a .38 Special with 148 grain to158 grain lead wadcutter or semi-wadcutter bullets.
I've seen too many 650-700 fps 148 grain wadcutters give limited to dismal penetration in various ballistic "non-tests" or bounce off target back boards, tree trunks, or hard packed earth to trust them for defense.
I once read of a night desk officer who was assaulted in a police station who used his service revolver loaded with target wadcutter .38 Special ammunition against his assailant. A 148 grain lead wadcutter was found to be stopped in the miscreant's left hand which had gotten in the way of a shot intended for the torso.
Apparently that was enough to take the fight out of the attacker as the story had a happy ending. So, one could say that the load served the purpose.
But, what if it hadn't?
The tale was used to illustrate the weaknesses of the use of light target .38 Special loads for defensive purposes. I didn't observe it so don't know if it was true, but could well believe that it could be so.
Something lead with full caliber shoulders, on the heavy end of the range of bullet weights available for a cartridge and traveling over 900 fps makes me feel better about penetration. This holds true for me in .32-20, .38 Special, .44, or .45 revolvers.
It must be said that far more critters and varmints, up to large feral dogs and an injured deer, have been laid low by my 858 fps 158 grain lead SWC handload fired from a 4-inch barrel .38 Special than all other center fire handgun cartridges I've used combined.
It's really the combination that has put the "Special" in ol' .38 Special for me.
