I've been working on a sub sonic load for my Blackout. I've tried 6 different loads all of which are supposed to be subs. I'm using the Lee 230 grain cast with powder coating. Accuracy doesn't seem to be a problem since I'm smashing clay birds at 100 yards. The problem that I'm having is that the velocities are too high! I'm using what they describe as absolute minimum loads. Average velocities are running between 1180 and 1250 fps. H110 so far has had the smallest spread. Any ideas on the wisdom of further minor reductions in loadings? So far, ejection has not been an issue. Yes, I am chronographing these loads.
