New Army 9mm Ammo Specs

[mrerick]

Is there a source for the information about Winchester's usage of specific powders in commercial loaded rounds?

I teach classes on reloading, and would like to incorporate such information.

This group has published a database of powder characteristics - for example:

https://ilrc.ucf.edu/powders/index.php


They list only one OEM loading powder (a Remmington powder) and no Military powders for some reason.

Here's the sample detail on HP-38 ;

https://ilrc.ucf.edu/powders/sample_...p?powder_id=82

Here's Winchester 231:

https://ilrc.ucf.edu/powders/sample_...?powder_id=397

It's a reasonably comprehensive powder characteristic database, and yet the powders listed are generally ones available commercially to reloaders. It's designed for forensic identification of powders found at a scene, so I wouldn't think they would limit it to just reloading powder (since we produce the vast minority of ammunition compared to OEM manufacture).

I'm trying to understand why Winchester would create a special powder just for their own internal usage, and yet it not be listed on this analysis database - which appears pretty comprehensive.

I would presume, from the introduction to the database, that they are limiting their analysis to commonly available reloading powders. The database is primarily used to analyze residue from IED's, not from residue from gunshot wounds. Again, the powders used by the factories may, or may not be commonly available. Lot to lot variations in bulk powder preclude use by handloaders seeking consistent results from various lots. Sometimes you will see bulk powders available for sale as "surplus" from pulldown ammunition, and they will tell you to cross-reference with a certain powder, but start loads must be "x" percent lower.

why is that box marked TRAINING down on the lower right?

It is sold as training ammo, as opposed to target or self defense;
i.e. "marketing".

Mrerick,

I have read that Winchester uses, what is commercially called, Power Pistol (an Alliant Powder) to load its regular NATO Spec ammunition. As stated above, it's probably delivered to them as a bulk type powder vs a commercial canister powder.
