I caught a heck of a deal on a hornady dispenser. It's given me fits twice with over-throw errors (that it catches and alarms for), but simply unplugging and restarting cleared it up.
I double check all of my charges on a balance beam (RCBS 505), I haven't had any variability beyond the 1/10th grain specification, which is about as good as I can hope to get on my balance beams anyway. And of course, I do my ladder testing to ensure that I'm within a wide forgiveness window such that 1/10th grain won't mean any significant change on my downrange result.
I didn't expect much out of the Hornady, but it's done me well. Had it for ~2yrs now I think, and I know I've loaded over 5,000rnds across it.
