Why only 1%? If they are as good as described above (and I genuinely hope they are, as someone who hunts and only shoots targets in preparation for hunting) these will take off like a rocket. People from the HFT circuits are already pricking their ears for the benefits. Word will spread like wildfire. Likewise with hunters... Air gunners are quite a well connected breed and word gets around. So the serious hunter/hft/pest controller will hear of the successes quite quickly.
As for the casual garden plinker? I'd suggest the vast majority probably aren't the ones buying jsb pellets and are the type (on the whole) that keep spitfires and bsa type pellets in production, solely on price.
However that still leaves one of my original questions unanswered... Will price fall as demand rises?
