I do the weight sort early because it saves all the other work-steps if you have an outlier. And scratching the case early, you're saving work, you;ve got to poke the stretch scratcher down into the neck anyway, so that's a good time to catch neck defects before sizing, trimming, etc.. Finally, I'll anneal before sizing because that usually prevents or makes neck cracks less likely when you finally size.
In fact, one time I was popping necks, two in the first ten, stopped right there, annealed the rest of the pile and they all survived sizing, priming, trim and chamfer and are still a good shooting batch with maybe 1 percent having failed through five reloadings. Not bad for free scrounge brass.
When you size, you can fit the FL sizing to the chamber and not get any more stretch that cycle, at least not in my bolter 223.
It's all judgement call, I guess.
