how is changing the cal. size of paintballs going to make it cheaper for people? 68cal to 50 cal means all new barrels, guns, shoot even a new squeege to fit down your new tighter barrel. Its going to make the 68 cal stuff obsolete there for making it harder to sell that gear. Now you have to go buy new gear and have a 68cal dust collector.
.... cause you know the 8mm airsoft BB took off.
