Full disclosure: I recently purchased a Hornady Lock-n-Load and had some drama knowing which primer system to use; the press came set up for large primers but I load 9mm which uses the small primers.
Anyway, when searching around to figure out what I was doing wrong I came across a few videos showing the RCBS APS priming system. Why didn't APS catch on? It seems so much easier to manage than mucking around with primer loading tubes dumping into feed tubes and relying on gravity (and the correct primer shuttle & punch!). CCI's site says RCBS is their "sister company", and the RCBS press is the only one I'm aware of that uses APS... so why didn't this system catch on?
