I load .38 Short Colt. However when I set up my powder measure I drop three charges into a .357 shell, and take the average.
I'm using a Dillon 750 with a bullet feeder and a case feeder. I check my powder charge every 1000 our so shells. It never changes.
I also check my powder charge when a change to a new bottle of the same powder.
I can't speak for you, but I'm shooting .38 Short Colt in a gun designed for .357 magnums.
When I first started shooting .38 Short Colt someone told me to start with 9mm load data, and work up from there.
Except I couldn't find any 9mm load data for heavy 160gn bullets, and even when I loaded lighter bullets they didn't give me the fps I needed due to the barrel gap in my revo vs a semi auto no barrel gap.
I actually started with .38 special, but couldn't get it anywhere near minor with the powders I had on hand.
When you find a powder you like, buy an 8 pound jug if you can find it, maybe two.
Same thing with primers, buy 10,000 if you can find them. Winchester small pistol primers are available at Target Sports USA. Federal seem to be trickling in slowly.
I load Bayou Bullets 160gr RN to 1.2 with 3 grains of Clays. I use a .357 sizer die, then a 9mm seating die and a 9mm crimp die.
I found Titegroup to be way too dirty in my revo.

Somebody here sells a multi port comp that supposedly works pretty well.
I bought an extended cylinder release he makes and it's top quality. I think Revolver Supply sells them.
This year's Christmas / Black Friday sales were unheard of. Up to 50% of on lots of stuff.
I assume they needed to raise cash due to people loading up at the beginning of the pandemic, and not because they're so friggin generous?
