Re: What first?
The thing about QuickLoad that makes it important is that you can measure case capacity in grains of water in actual fired cases from the rifle you're working with and feed that data to QL. This has often had a huge impact on the data I get for a given rifle, and I have yet to see QL off by a large margin when given complete/accurate data.
So, when I get a speed off a charge, I can refer to the QL tables I get for that specific rifle and get very close to the true chamber pressure values and know exactly what I'm working with, instead of trying to read the tea leaves by looking at the cases.
I've found that primer appearances are incredibly unreliably indicators. Different brands and different lots react differently, and I've seen badly cratered primers that would make folks pale at the look of them and they came from moderate charges. Take the same components and goose the charge a bit and the primers look fantastic. I've seen that more than once.
Primer pocket loosening I find is a good indicator, but you get that "after the fact" and the damage is done at that point (at least, to the brass).
But using velocity and good data, you can know within a pretty narrow margin of error what you're dealing with and spare a lot of headache and time.
Working with some friends from another forum, I've managed to put together a loadwork process that seems tedious/time-consuming, but in reality, it's yielded hunting-capable (or better) accuracy for about a half dozen rifles inside of 50 rounds fired per rifle.
