Looks like I am in the minority on 32 ACP + 244 powder. I'm posting in case anyone is looking for data.
71 gr Berrys .312
Powder - Win244
Primers - Remington 1 1/2 Small Pistol
OAL - .980
Press - Dillon XL650 w case feeder
Dies - Redding 32 ACP Pro Series Titanium Carbide Pistol Die Set
temp 66 deg F. alt 800 feet, humid 70%
==============================
2.1 gr Win244
Scorpion 4.50" 903 fps (some stove pipes, too weak)
Savage 3.75" 710 fps
CZ50 3.75" 837 fps
================================
2.35gr Win244
Savage 3.75" 876 fps
CZ50 3.75" 899 fps
===============================
2.4gr Win244
scorpion 4.50" 985 fps (better cycling)
Savage 3.75" 923 fps
CZ50 3.75" 947 fps
==============================
fiochi 73 gr factory (loaded to Euro standards)
Savage 3.75" 939 fps
=========================
32 acp 60gr sellers factory
CZ50 3.75" - 939 fps
I think 2.1gr is on the verge of too low, at least for my guns. The savage really dropped velocity over the tighter chamber of the CZ50 at this load. If you notice at 2.35 gr both the CZ and Savage are closer. My best guess is the Savage was able to seal the chamber better at 2.35gr vs 2.1 gr. At 2.1grs the CZ was quite a bit faster.
I'm thinking my do all is going to be around 2.3gr, gives me a larger margin of error, don't want to cross the 2.5 gr barrier.
Redding dies are good quality but the sizing die needs to size a few mm further down the case. as is 20 percent of the cases will be out of spec and not chamber well.
