Reloaded Some .380 ACP Today

Today for the first time I reloaded .380 ACP cartridges. They will be used in my Ruger Security-380.




I used a mix of PMC and Sellier & Bellot brass, Aguila primers, 3.4 grains of Winchester 244 powder, and Berry's 100 grain plated lead bullets. The data I consulted suggests that this will give around 900 - 925 FPS at the muzzle.

Assuming it functions well and is accurate in my gun it will make a good practice load.

I also figured out the approximate cost per round of this ammo, not including sales tax, shipping, or HAZMAT fees for shipping powder and primers.

  • Cases: Free (Saved from fired factory ammo.)
  • Powder: $0.02
  • Bullet: $0.12
  • Primer: $0.07
  • Total: $0.21

Comparable S&B factory .380 FMJ ammo: $0.40 per round.

After I was done out in the shop I ordered a 6-cavity Lee TL356-95-RF mold. This will cast 95 grain round nose, flat point bullets suitable for use in .380 and could also be used in 9mm, although I generally like 115 - 124 grain bullets for 9mm. This will drive my cost per round down even more.
