Maxam CSB-1M Pistol powder

So..... I went ahead and pulled the trigger and order a case of this Maxam CSB-1M powder. Supposedly the parent company of RIO for shotgun. They actually have pistol data listed here http://www.maxamcomponents.com/media/Corporation/Outdoors_Brands/Componentes/MAXAM%20Components%20Catalogue%202015.pdf
I have read of CSB-1 but didn't see any mentioning of the "M" version aside from it was a tad bit faster than the non "M" version. Anyone else have experience with this or its variants? I hear many people say its similar to Hodgdon Universal. But could the "M" version might be closer to Unique?

The link you posted is quite useful. That is where people should be getting CSB-1 load data from rather than second-hand info from those who are just repackaging it.

Anyway, I think CSB-1M is just smaller grains, to meter easier.

Yes. LOTS of confusing and CONTRADICTING information on the various CSB powders. Some places to have appeared to mislabel CSB-1 as CSB-6!!! And others totally rename the damn thing into their own proprietary branding, not cool.
A big thumbs up goes out to hi-tech. Says it is sitting on a cart waiting for UPS to pick it up in the next couple of hours. FASSST shipping. Probably had all those kegs of powder in a box waiting for a poor sucker to slap a label on it :-D
