As a general rule, if the solder isn't flowing you need to give it more heat.
No way around it.??

Except for plastic parts like the connectors, it's astounding how much heat this stuff can take.
Hot air rework on large parts with lead free solder is way worse then what I do with my iron.
Don't tug at the part or you'll lift the pads off the board when removing a part.

Thank you both. I'll use a bigger bit and 440C and see how it goes.
I built the QMX and QDX with a similar iron to that one Jerry but perhaps I was just a little shy with the heat. I didn't like going over 420C. I'll experiment on the QMX first as it's a bit the worse for wear.
