The load time for me is roughly 5-10 minutes when starting theA13 if anyone is interested. I do have a strong gaming laptop (yes, laptop). The load time for A12D was around 30 seconds to 1 minute.
A13 version is still in dev phase.... so don't expect it to be perfect at the moment. Just open game and go make sandwich or tea 
I had problems with ammo not being picked up by colonists - and looks like it's because of mod order and prepare carefully mods implemented into modpack so... yeah. Be patient 
I was asking about the times a couple of posts back, he should of referenced me rather than if anyone's interested. at least I assume he is because of the post I made asking about it. And to give a small explanation as to why: It's because It's not unique to this modpack so whether your running the dev alpha 13 of Hardcore SK wouldn't have any baring on the load times. I've done some research in that it could be related to sound files each taking 3.00 seconds each to load or some such.
Reguarding the latter, I found If I loaded my save idk say about 10 or so times my game would become bugged in that certain features would be locked in that I couldn't use group attacks, couldn't change beds etc. But competently restarting the game, and It'll work fine for so many load attempts (it may or may not be related who knows, this is the problem I encounter but I know its dev, and I'm fine with it (Well technically not really but, I'll put up with it to play early Hardcore SK alpha 13, and if I can report a few bugs and speed it along why not a?)
