I downloaded Vectans reloading data manual, but would like to find more load data. Most of the usual suspects online have little to no data on it. I haven't bought a new reloading manual in a couple years either, so don't know if they are starting to publish data for Vectan powders in some of them or not. Anyone know of any manuals that are showing a good bit of data for Vectan powders or an online source that contains a fair bit of data?

I can tell you that with tubal 5000 it is not possible to fit enough powder in a .223/55gr or .308/150gr to make velocity let alone cause pressure, even with a drop tube. Didn't make groups worth a damn either.

Didn't meter too bad for a stick powder though, and it's cheap.

Found a few more downloadable PDF's & some data on a few reloading sites.  Graf's also had a Vectan reloading pamphlet you could get for free.  Not as much data as I'd like, but that's typical of the free pamphlets.  At least I have one hard copy with data on it.

In my experience, in 9x19, Vectan GM3 loads nearly identical to Alliant Sport Pistol, with same charges getting same velocity.  It is a place to start.
