I'd say 15-20 minutes with a progressive press, provided that you have the dies set up already and the brass is tumbled and visually checked. You won't reload that few in one go, better load 500-1000 in one go once you have the recipe sorted out.

I have a simple single die press for revolver stuff and use Dillon 550B for "mass consumed" ammo like 9mm, .45acp... no .223 yet on the list but shouldn't be too different with once-shot or pretrimmed brass.

Presses that autoindex and have stuff like case or bullet feeders are way faster. 400-500 rounds an hour with a 550B is the norm.
