I've been reloading x39 over the past 4 years.
Finding once-fired brass isn't so hard (I've stockpiled about 2K pieces) in part because so few people DO reload it.
Saying it's not worth the time to reload x39 is somewhat myopic unless you're comparing your effort/costs to top-quality brass-cased ammo rather than the same cheap import stuff. A box of Hornaday Z-Max runs for better than $21 a box (if you can find any). I can make it for less than $6 per 20.
And I'm reloading for my x39 AR, so the gained accuracy of my reloads over that of Wolf, Tula, etc. is quite apparent.

“It does not require a majority to prevail, but rather an irate, tireless minority keen to set brush fires in people's minds” — Samuel Adams
