Fluff, something else I've always wondered is the HW100 actualy 100% Regulated or is it semi regulated? I've heard so many people say this and that etc, and to be honest semi regged what the heck does that mean
It has a mechanism that equalises the velocity from shot-to-shot, so yes, as far as I'm concerned, it has a regulator, even if the reg design is unconventional by being external to the air cylinder.

Here's a full-fill shot-string from my .177K taken during my tuning process (s/n 1909043, 11.1ftlb average energy across the whole charge), using unsorted JSB's/AA's (with known variation of 8.2-8.7gn, which accounts for most of the shot-to-shot ft/sec variation if you do the maths).
