I use the Speer #8, and I don't care that they used crusher data, for loading my 160gr LSWC, whether it is in long or short case.

I have to admit that I'm not loading many Speer #8 max loads of 4756 with 125 gr bullets any more. When I figured the difference in energy between the 125s (729 ft lbs) and a 168 gr SWC at 1400+ (752 ft lbs), I've pretty well converted to 168 gr. That's about 60% of the available energy of a 55 gr .223 at 3200 fps.
