.686 or .689 diameter
I got the X-Ball Bronze to try out and was really impressed. The day was very windy, but even with that these balls flew straight. Strangely I played against the wind nearly the entire day. The fill was a little thin, but it marked very well. The ball diameter was small about .686. Out of the whole case I had 1 barrel break.
These balls broke on evereything and everyone I hit. Excellent paint for the speedball field. Get this paint. My rating is a 9 but I haven't found a better paint for my gun. There is always room for improvement though i don't know what to improve on this paint.
