Just to be clear, we are talking about the .38 Colt Automatic, not the .380 ACP?
Right?
Cartridges of the World shows:
130 grain FMJ bullet.
4.2 grains Bullseye.
1,040 FPS.
312 ft/lb ME.
This duplicates factory ballistics.
I don't have any lead bullet data right off hand.
But I would expect 4.0 grains to give about the same velocity with a lead bullet.
