I hear ya ... too bad we can't get you some W231/HP-38. These are from powder manufacturers' product pages. As you can see (with the exception of W231/HP-38), most are shotgun powders with secondary use as pistol powders due to their faster burn rate and cleaner burning characteristics even at lower target pressures with the exception of WSF (slower burn rate powders require high-to-near max powder charges for more complete burn to produce consistent chamber pressures that results in accuracy).
If you have to commit to a total of 8 lb purchase (remember, you can buy 2 4 lbs or 8 1 lbs or a mix of 1/4/8), you can't go wrong with W231/HP-38/Zip for 9mm/45ACP and Clays/WST/Green Dot/American Select/WSF second for me. If I had to choose powders that came close to W231/HP-38, American Select/Green Dot. I would choose WSF, if you were considering loading full-power loads along with lighter target loads. Just keep in mind that there are current 9mm/45ACP load data for Clays/American Select/WSF.
