Silhouette/WAP in .38 Special

[Charles]

I know the conventional wisdom for years has been that this would not be a great combo, but Ramshot now includes data for both .38 Special and +P for Silhouette. I found a couple thousand 170gr keith style SWC bullets specced at 12 BHN while moving recently, and am about to load some up for a model 10-8. I also have a pound or so of Silhouette. I'm wondering if the extra weight would help give a good burn? Does anyone have any experience with this combo?

Thanks,
