I have a Hornady Auto Charge, I added the same reducing insert you can get for the RCBS Chargemaster Combo. It really reduces the overthrows with the problem powders. Just watch the videos of adjustments you need to make to the speed for certain types of powders.
Anyway, I'd have confidence with either one, but really only use it for smaller batches. .45 Colt of lets say 50 rds of Unique. Also for most Rifle loads of 20 or less, it's just to slow for my heavy reloading batches of 300+.
BTW, don't forget you can get $75 off on the RCBS, also if you can wait the Hornady usually goes on sale for under $180. I picked mine up for under $169, just waited long enough for it.
Little hints? Make sure you let it stabilize by warming it up for a minimum of 15 minutes, and get the reducing insert. It's just more consistent and it won't wander.
