ADI exports a range of propellant to the US market where they are rebranded by Hodgdon Powder Company. We share reloading data and technical information with Hodgdon, which helps keep our products at the cutting edge of performance and quality, also the sizeable volumes of Aussie-made powder we export to the US help keep local manufacture economically viable.

Spot on a lot of the ADI powders are relabeled for other markets in which case the data is interchangable. There are others as well win296/H110 springs to mind


Hodgdon HS-6 is equivalent to Winchester 540
Hodgdon HP-38 is equivalent to Winchester 231

Hodgdon makes good gunpowder. I have loaded several match winning cartridges with Hodgdon gunpowders.

Not sure of the equivalent to any other powder, but, I've found a very good load using Alliant BE-86 for the .357 mag/158gr XTP's. Working on same powder with 250gr RNFP Missouri bullets for the .45 Colt. Looks promising, will report when I try the .45's. 357 were superb in accuracy and velocity from BBB, 20" barrel.

There is one thing that's important to remember. Just because a particular gunpowder is listed next to another on a burn rate chart does not mean it's close in burning characteristics. Some gunpowders are position sensitive and some are not. Some listed close to each other on a list may generate significantly different amounts of pressure.

Be careful out there and don't forget to have fun.
