CFE-P works well for me to load serious stuff, meters decent.

4.0 is the listed max with a 100gr bullet, don't use the Xtreme bullet for serious stuff but for practice.

Almost had to laugh the ES and SD were the same for both!
The CFE-P load is pushing a 5gr heavier bullet about 20fps faster.
Hodgdon shows some good vels with W244 but I haven't had a chance to try it in .380 yet.
