I have plenty of this powder and would like to use it for 9mm, 40, and 45acp. I read it can be used for 223 too.
Finding data is hard and then there's the CSB-1 mystery, if it's actually the same stuff or not.
I have some hi-tek coated 200gr 45acp ready to load. Expansion Industries data looks odd. I'm used to lead bullets using LESS powder the FMJ. Their data lists lead as MORE powder than FMJ. Is that a typo?
I've researched lots of forums and many are using 4.5-5.5gr, no where near the 5.8-6.3 Expansion lists.
Here's a link to their 45acp load data.
