I totally agree, at sub 12 power they do not expand as they might at higher velocity, however, they do make a hell of a crack when you hit something, and having used them for a while now, absolutely everything I shoot with them is lights out,I have never been a fad pellet fan, but these break the mold, super accurate in my Brocock s6, I am half tempted to add an fac air rifle to my ticket, I reckon in .22 or .25 at 30+ ftlbs they would be amazing, mushrooming out very well, hmmmmm food for thought.I want them just for the sound now... through my 98 running close to 12, should be a match made.
