What part of the case prep are you held up at?
I've halfassed my way through loading lots of stuf even to the point of setting a case on top of a shell holder for sizing and then tapping the case out with a dowel.
Seating dies don't tend to hold the case so you could probably adjust the seat die up and seat with the case sitting on top of a shell holder too.
Priming is the problem without the proper shell holder.

I have a bunch of sized, primed and flared cases I could swap you or send me your brass and bullets and I can load them up for you.
