So, cue lots of google searching and cursing thinking that I had done something wrong....nope, turns out that the HY/RD calipers are designed to work with the 11-sp road levers sets that have a longer cable pull than my 10sp lever set (the only 10sp levers they will work with are the Tiagra 4700, which has the same cable pull as the 11sp series)
So, off to youtube looking for hacks, searching on BNA etc. Anyway, I found a temporary fix, which was to just unscrew the pinchbolt from the top of the arm and attach it underneath instead, then route the cable under the arm instead of over it, and that gave me enough pull to stop the levers bottoming out.
In the meantime, I found a guy in the USA who sells a Short Pull version of the Actuator Arms, which are designed to work with the 10-sp levers that have the shorter cable pull. He should have stock again in about 3 weeks, and that will make the calipers produce the right amount of lever throw. If I ever go 11-sp, I just fit the original actuator arm.
I fitted a set of HY/RDs to some Ultegra 6603 levers a month ago. You are right, it was a complete pain in the posterior to do, but with good cable routing and by really ensuring there's no slack at the ferrule/ lever interfaces they work well.
