Anybody have any data for the '06 with Alliant Power Pro 4000-MR and a 180 grain Speer BTSP?

All I could find is this: Alliant Powder - Reloader's Guide

I was just going to go with the data linked above for the 180 grain TBBC, but just substitute the BTSP instead, but my Speer manual says only to use TBBC data for TBBC bullets because they behave differently than conventional bullets.

The data for the 180 BTSP, on the Alliant website, is showing RL 17, but I can't find that anywhere. Truthfully, this 4000-MR is the only powder that I've seen on the shelves this year.

I've been all over the 'net looking for info to no avail. I have already emailed Speer and Alliant, but haven't received a reply yet.
