As John D mentioned, Hodgdon H4198 is the same powder as ADI AR2207 - check out the product info for the Hodgdon powder - made in Australia... https://shop.hodgdon.com/hodgdon-h4198/
So you can use load data for H4198 when using AR2207. I use 2207 in my 222, the reloading data is the same on the Hodgdon website for H4198 and ADI website for AR2207
