What do most do when powder only list a max load value? I have noticed on the Alliant Reloader's Guide for BE-86 (really only reference I can find for BE-86) that they only have max data. Normally I'll start halfway between min and max values and work my loads up. With only having a max data point, is it best to just drop it by 10%-15% and start there?

EDIT - I guess I should have read the legal disclaimer before asking the question...
REDUCE RIFLE AND HANDGUN CHARGE WEIGHTS BY 10% TO ESTABLISH A STARTING LOAD.

Yep. Standard rule of thumb is reduce 10% and work up. Also, you should do this when changing any component. Swap Zero for Nosler 180 grain JHP...Reduce 10% and work up. Swap CCI for Winchester primers....Reduce 10% and work up.
