I'll sub load data for closest possible weight. But there's definitely variances in data for similar weights but different bullet shapes. Like gajin mentioned the bearing surface can change pressure levels a bit.
Powder lot variances have shocked me too in recent years. I don't like to waste time starting too conservatively on the other hand. Common sense and a little cushion for safety go a long way.
