Steve, been away quite a bit here lately. As to .380, I locked onto Jack and I believe Fred's recommendation of 2.8gr W231 under a 95gr Missouri Bullet, .098 COL. In the P238, it makes for some very effective rounds and does not wear you out.
I know it seems counterintuitive. But this load is not harsh. It's very smooth really. It's a little shorter then the load in the manual, it's only .1 gr over the starting load. I would doubt it's even past a mid level load in 380. It does shoot nicely.
