anyone use quickload?

Johnny,
Thanks for the reply
I have the sierra book, and use their bullets, it is a good format. I have never called them, but the number is on the first page of the book. I like that they give velocities and best accuracy and hunting loads.

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.
