Red Dot is my go-to powder for anything 9mm. It’s a fluffy powder that fills cases nicely. But it can also hit max pressure quick. So carefully work up loads. But generally speaking, I’ve had fantastic luck in the 4.0-4.2gr range with 125gr cast loads. No idea where this sit speed wise, as I don’t own a Chrony. But they function the guns I run them in well, and accurate.
