380 is one of the easier rounds to load for in my opinion.
First, it is almost impossible to double charge the round. Nearly every powder would spill out!
2nd, there is a widely available components.
3rd, it is an easy one to hot rod, but not to far!
My favorite load is nearly engraved in my head. .984 COL, 4.0 grns of Unique, CCI500 primers, Starline brass, Seirra 90 grn JHP or Remington 88 grn JHP.
Great load, depending on the gun it does between 900 and 950 FPS and is reasonably accurate.
