Winchester AutoComp (WAC)
A competition powder that is versatile in 9MM
Hard to get a clear pic.

Winchester AutoComp (WAC)
A fine flattened ball powder.  A lot can fit into a case.  More than you will ever need.  This makes this powder more dangerous if you make a reloading error.  Very similar to CFE Pistol, except test after test after test, we found WAC to be more accurate.  This is no coincidence, its consistently just more accurate in our testing.  We tried many loads to compare, retested, and over and over again, its consistently more accurate.
This ranks up there as one of the best powders you can buy for 9 MM.  Its top tier.  It looks and performs similar to Ramshot Silhouette for example.
