Warner VLD bullet Ramshot powder federal magnum primers COAL 3.766 Not sure about the min max powder charge since this isnt a typical load. Any help would be great.

Never loaded it myself, but they do list some data for Ramshot LRT at the link below. No Magnum data

Based on your bullet, I'd be comfortable starting at the low end of the 200LRX bullet listed, since the Barnes bullets are typically longer than most and would probably be an "equivalent" size to base starting loads off of for your long VLDs.
