Power Pro 300 and other USA-made Powders

[john 800]

I picked up a pound of Alliant Power Pro 300 for loading 357 today and while I was reading Alliant's statement on it I was surprised to learn it is made in the US. Its news to me that any powder that is available as a component is U.S. made. Are there others I am not aware of?

Possibly a St. Marks powder made in Florida?

Possibly a St. Marks powder made in Florida?

According to their website, St. Marks
Powder produces more than 95% of the powders consumed by the US military and dozens of powders for consumer use.

Speaking of stuff sold in the US:

Most ball/spherical powders consumed in the US are made at the GD (General Dynamics) St. Marks facility.
The only ones that aren't are Ramshot (from PB Clermont in Belgium) and the Shooter's World spherical grades (from, I believe, Explosia in the Czech Republic).

Most flake powders consumed in the US are also made in the US, at a NJ facility (owned by I forget who). Some are made by GD in Canada.

All IMR rifle powders (as sold in the US) are made by GD in Valleyfield Canada (except IMR8208XBR, which REALLY, REALLY is misnamed and should be called H8208, because it's part of the same product line as the rest of Hodgdon's extreme line).

All Accurate extruded/stick powders are made by GD in Valleyfield Canada.

All Hodgdon's extreme line are made by ADI (Thales) in Australia (plus the aforementioned IMR 8208XBR).

Vihtavuori powders all come from Finland.

Alliant's Reloder (plus AR-Comp) powders either come from Norma (Bofors) in Sweden or Rhinemetall Nitrochemie in Switzerland.

Shooter's World stick grades also come from Explosia in CZ.
