I'm sure all re-manufacturers are not the same, but it's generally good quality and safe.
One of our local PD's uses re manufactured practice ammo and a Sheriff's Deputy friend of mine went through a lot of it before he bought several Dillon's.
I purchased a bunch of old re manufactured .38 Special a few years ago for $3 per box (50). I probably have 1,000 rounds left and I haven't had one dud yet. Shoot-O-Rama reloads rock!
