I guarantee none will be to loose.
Some may not even accept a bullet and crumple under the pressure. It really needs to be the right size.
What would be result if you entirely withdrew the depriming pin and its rod assembly from the die and then you resized the case?
It would be sized perfectly and be ready for loading.
Provided they were neck turned and full length sized with a bushing style die.
I de-prime and clean before anything else as well.
I grind down, or replace with a smaller button, the expanding ball in my sizing die so I can use an expanding mandrel instead.
Using a mandrel keeps the neck and shoulder more concentric. Leaving the extra de-priming pin in the sizing die ensures there is nothing occluding the flash hole, or I didn’t miss a primer, on the second run through. And because there is no work done on its removal from the case, there isn’t a real reason to take it out of the die.
Of course, with pre-processing, there isn’t a real reason to leave it in.
Shooters choice really, in this instance.
Just as long as every step is done to every case the same way.
I’ve been trying(/failing?) to teach my kids that it’s a lot harder to do things the exact same way, every single time, every single day, than they think it is.
