I recently picked up an Astra 400 chambered in 9x23 Largo and .38 ACP. Eventually I will buy some largo brass and reload that, but for now I will be reloading .38 ACP since I received a bunch of that when I got the gun. The problem is, I cannot find any load data for .38 ACP. It is the older brother of .38 Super, but if I try to load anywhere close to those specs, I will blow the gun up. Does anyone have a source for load data for obscure rounds? Thanks.
