Pretty much what pgrich and mykeal has said. In addition:
I use 25 gr fffg in my .44s; but 20 works and may be more accurate in your pistol. Results vary.
If you use the wads between the powder and ball, the lube on the chamber mouth is redundant - and messy.
Sprue up or Sprue down is six of one, half dozen of the other. I always put them sprue down
You shouldn't have to pinch the caps to keep them on the nipples, if you do, they are the wrong size.
Some kind of antiseize dressing is necessary on the nipple threads. I just use Balistol on my nipples to keep them from seizing. Of course I take them out an clean them after every match too.
