I have a question for some of you seasoned reloaders. I am working up a load for a 165gr in my 30-06 and am just finishing up a load with a 150gr bullet. My question is this: When working up a different load (changing powders or bullet weights), is it to be expected that the new nodes will occur at the same velocities as the previous nodes where the charts overlap? What I am getting at is this: If I have a previous load vs. velocity chart and I have reason to believe that my new load will produce a given node velocity at a given powder charge, I may be able to speed up the new load development and reduce supply used by choosing to only load a smaller subset. Of course the assumption here is that the bullet weights are close enough (or the same) so that velocity curves overlap significantly.
