.452 250gr load data in acp

Buddy got some 250gr hornady xtp .452 bullets instead of a .451  he's using Winchester 231 powder.  All either of us can find is to use 5.1gr for 800-900fps.

Does anyone have any other info on that setup by chance before he starts testing?

231 is a clean choice for 45 ACP.  I don't have any experience with that bullet but getting the cases all the same length with a  taper crimp should produce some accurate stuff.
