SWC= Semi-WadCutter, FMC= Full Metal Case, FMJ= Full Metal Jacket, JHP= Jacketed Hollow Point and if GC indicated, means Gas Check at bottom of lead bullet.
Loads for .38 Super Auto: *
These are NOT for the .38 ACP (same case length) and certainly not for the .380 Auto/ .380 ACP. (Note: These ARE MAXIMUM loads, you may want to use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.
These are ALL MAXIMUM LOADS: Start at 10% less and work up! Bullet size is .355″ (9mm) (jacketed or lead) in diameter. Some loads use a .356″ bullet.
Note, where you see HP-38 you can use Winchester 231.

Discussion: * The 38 Super is a very high power version of the 38 Auto or 38 ACP. (Thanks to Ross for info on 38 Auto) The case is much longer (.680″ vs. .900″) and the powder loads are almost double in some charges. Since the 70’s, the 38 Super cases have been designated +P, showing they are more powerful that the .38 Auto (.38 ACP) that appears the same size. The 9mm Luger with a shorter case (.754″) matches the loads pretty closely, but 38 Super+P is still more powerful than the Luger. The .380 Auto is a shorter case(.680″) and should not be confused with this caliber.
Unique, Universal and No. 5 which are moderate fast powders are well suited to cases like the 38 Super Auto. Even slower powders with these big charges for this small round can produce higher velocities and lower pressures.
A bullet with a copper gas check or copper plating is best for INDOOR ranges to keep lead vapors out of the air.

I’m having trouble loading new cases in 38 super auto. I’m using Hornady 124gr XTP bullets that are 357 in diameter and no matter the flare on the cases, they are hard to seat the bullets in the cases. I’m using Redding dies and the seater plug is imprinting the cases heavily if it even seats them without buckling the case. Would using the .355 diameter XTP bullets in 124gr be better for this load? Specs in Loaddata written by Brian Pearce doesn’t mention anything about XTP bullets of different diameters being better than the .357 ones and I happen to have several boxes of the .357 XTP’s.
Don’t care who MD Smith is. And I have no clue who Ross is that got thanked for his information on the 38 ACP? But they were wrong. It is incorrect stating the 38 ACP is a shorter case at .680”/17.3mm. It’s a 22.9mm/.900” same as the 38 Super Auto +P. This information can be readily found in Lyman #49 & 50, Hornady #10 and most importantly in the current SAAMI Voluntary Industry Standards for Pressure and Velocity of Center Fire Pistol and Revolver Ammunition (SAAMI Z299.3-2023) page 41 in the cartridge and chamber drawings. The 38 ACP has always been a 23mm length case, not shorter. Therefore the 38 Super is not a lengthened version.
