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.
