I think my statement could possible be taken as I am stating it wil ALWAYS out perform .68 cal, what I said was I have shot a .50 and a .68 side by side both at around 280 fps and the .50 shot further than the .68 so it was that test and that time that it did.
You're splitting hairs. A 1.21g or 1.28g .50 cal paintball will *NEVER* out-range a 3.2g .68 cal paintball when fired at the same velocity. So if you stand by your previous statement, then you MUST have had a .50 cal paintball that weighed 1.5g or more.
I can GUARANTEE that if you take those 1.28g .50 cal paintballs and fire them at 280 fps and take some .68 cal paintballs and fire them at 280 fps, out of straight-cylinder barrels, that the .68 cal paintballs will go further EVERY SINGLE TIME.
So the paint that people will actually get in the cases they buy - will that be the .50 cal paintballs that you don't have any more of that you claim out-range .68 cal paintballs, or will that be the .50 cal paintballs you have now that don't actually out-range .68 cal paintballs?
Addendum: .50 cal paintball needs to weigh about 1.6 grams to have a similar trajectory to a .68 cal paintball at 300 fps, although this is according to calcs by people smarter than I.
