Doublespeak. The powder is a 'common commercial powder' yet has not match for handloaders.
Common, yet not common.

Pretty much. It is physically undistinguishable from CFE 223. I took a pic of the powders side by side and unless I knew which bowl was which I would not have been able to tell them apart. I still suspect they use a common commercial cannister powder and by common it is one they use on multiple loads for economic scale.
The 6.5 123gr ELD-M bullet is also almost exactly the same as the SST. The ELD has no cannelure and a darker tip. Both the SST and ELD are the exact same length from base to tip and from base to ogive. The factory load in both appears to be the same powder and both are loaded to 30 grains.
The jump to rifling with both in my Odinworks barrel is 0.04" with measured OAL on both factory SST/ELD-M cartridges at 2.24" and 1.66" to ogive. Given that both bullets are secant ogive I suspect that loading to 2.26" might be more accurate.
