I have the Chargemaster as well, and have the brass reducing insert that I bought on eBay, which makes quite a difference. I saw a couple of head-to-head reviews on YouTube between the Chargemaster and the Hornady model, and let's just say I chose the Chargemaster. I will let you go check out the videos and see if you come to the same conclusion. I say this because it was not me doing the actual testing, and everything you see on the internet (including this post!) you need to take with a grain of salt. If I did the comparison testing myself, I would more strongly recommend one or the other.
One thing to consider is the RCBS rebate that is going on until the end of the year. $75 rebate on $300 purchase, which is pretty nice. You can get the Loadmaster for under $300, so you might need to add some small RCBS item to get it over $300 (like a trickle charger or a bullet puller or something...). Also, it looks like Midway and Natchez are advertising that the RCBS rebate is get $75 back on a purchase of $275, which is pretty amazing, but I am not sure if this is a Black Friday deal or what... If you can get the Chargemaster for $200 (after rebate), that is a pretty compelling argument to consider the RCBS model over the Hornady in my opinion!
