I agree. Nevertheless, in Canada and the USA, insurance companies ues ASTM standards and those do not allow firing above 300 fps, even for paintballs of caliber less than .68. And yes, that makes it a serious handicap going up against .68 caliber in anything but close range interaction.It would seem silly to treat it the same as .68 as it is a totally different product with totally different characteristics and thereffore needs its own set of safety rules and criteria.
It would be fine in a renter ownly environment, but more and more of my customers are showing up with their own gear and I doubt that many would choose .50 cal over .68 cal knowing they would be severely handicapped. I barely even get a group anymore that doesn't have at least one or two gear owners in the group. And since we are trying to expand the market and get more people interested in paintball, it's only natural for more people to want their own gear, so renter only groups are becoming fewer and fewer. The whole .50 caliber idea doesn't seem to fit into our business plans.
Having said that, I have no problem stocking .50 cal balls alongside .68 cal balls, should there be a meaningful demand. As it is, to date, I've had only a handful of customers even ask if we might start stocking .50 cal paintballs. And most of those were people asking just out of interst because they see the debates going on in forums, such as this one, not because they were seriously thinking of converting.
