Mainly wondered if quickload would give good data based on seating depths, and diffrences in powder mfg.
So i other words if I have a load that is in lc brass, varget powder, sierra 77 mk, seated with .100 jump or .020 jump, known velocity, what would be very similar if I changed to reloder 15..

Those kinds of questions. Yes I know I can load some up and shoot them to see what they will do, but if I have a little forecast of what may be better, I would concentrate on that.
Too many variables... you will have to go hands on with a practical application to get the answer IMO. I think it's best at estimating velocity... but I don't know, never used it, just hear people referring to it for start load data with different powders.

ADDED- it mentions bullet seating depth estimates are "crude", in other words... a rough guess.
