Man, some people won't be satisfied unless they're hung with a new rope!
But hey, who uses N320 for 9mm loads anyway, right?
Apparently only you! There's a reason they didn't list it. They tried it, found it too fast for 9mm!
Or just not accurate.
I came up with 155 loads for 38 special. That's counting the +P loads, if you can't find something with that selection, then maybe you should give up reloading, shoot factory.
