A heavy bullet published load for Bren’s .380
*Lyman cast bullet handbook- Some .380 are blow back operated such as Walther’s and such, invoking some caution and restraint. Others like SIG, Glock, Kahr are locked breach and more suited to some variables in loading. Blow back guns change in dynamics with bullet weights. FWIW
I’d not hesitate to use this data with 124 gr. cast bullets as a foundation to work up some loads. I have never loaded .380 nor have dies. I am thinking of trying with .38 Special dies which are very close, just to see. Maybe use the Luger to seat if it’s needed. I garnered some .380 brass at HHC so it’s on!
