I agree that quickload is just another "thermometer" but I'm finding it much more accurate in todays world than reloading data that has gone crazy soft.
What I do like about quickload and will say IT IS VERY USEFUL is that when working up a load I ask it what's the fastest I might be able to push a bullet/barrel length combo. It will give me all the powders near say 65k pressure. I usually set about 50 fps slower than the top few combos as a "top end" load. That very often is where I see pressure signs with most my guns.
It also useful to use the "step up chart" like that above once you've chrono'd a load to work up a little quicker. Sometimes quickload seems dead on but sometimes it might not match and be 4% off.
And I ALWAYS look at data from other sources and draw a balanced approach to work up. I would buy quickload again in a heartbeat but I do enjoy and do a fair amount of reloading.
