Yeah, both inserts can be handy but I now use a Redding Instant Indicator die instead of the Hornady headspace insert. The die is in my Redding T-7 press, set up and ready to go with a marker set at the maximum shoulder length. If it is over that then it gets a run through the Forster shoulder bump die in the next station. I could (and maybe should) use the Redding Instant Indicator for measuring bullet seating depth as well, but it isn't quite as straight forward as using the Hornady Bullet Comparator.
