I've known this for about a year, since I read something about it on the Pyramidair blog and did a little testing of my own. I found the "artillery hold" always gave an increase in power over the death grip, and I found this was true for my HW97K, my HW80K and pistols: HW45 and Webley Tempest.
Now I'm not bad at the geeky science bits but I can't think of an explanation for that one!
