Could be worth experimenting depending on load density. In my experience I've never really had to stray from .050" jump. Everything shoots so good I haven't felt the need to mess with em. I loaded (x3) at 92, 91.5, 91, 90.5, and 90gr. Hopefully I'll get to test after work today. Coal I believe is 2.800 ogive to base and 3.39".
