Thanks for the replies.
I have been happy with Universal in my jacketed loads. I was considering trying W231 because I like the way it meters in my Lee auto disk (I sometimes use it for 9mm and .45 acp), but my manuals suggest Universal over 231, and I have read claims (on the internet) that W231 can be position sensitive, don't know if that's true though. So when the bullets arrive I'll probably start with Universal. I like Red Dot in .45 acp so I might try that too. I'd like to try Unique also because, depending on who you talk to, 8 or 9 grains of it is the old standard load.
