History and Design
It is essentially a .45 ACP case, necked down to .357 caliber diameter, resulting in a cartridge similar in form to the earlier .30 Luger and .30 Mauser cartridges. It was created to be a low recoil target cartridge that would function reliably with multiple bullet types, FMJ to cast lead wadcutters without the feeding problems that straight walled pistol rounds sometimes exhibit.[3] The cartridge can be used in standard .45 ACP magazines.[4]
The .38 Casull followed the same forumula as the .38/45 Clerke, but with thicker case walls as in the .45 Winchester Magnum.[5][6]
Ammunition and Handloading
Brass .45 ACP cases can be resized to handload .38/45 Auto cartridges [7] using form and sizer dies still available from the RCBS Corporation, p/n 56468.
Nearly any 45ACP 1911 pistol can be converted to the 38/45 cartridge with a replacement barrel, from a 38 Super barrel reamed out to .38/45 dimensions,[2][4] and during the rounds initial popularity, drop-in barrels were available from makers like Bar-Sto.
