I was given a Columbia 300 women's ball. There is no weight marked on the ball anywhere that I can see. Can I tell from the serial number? The serial number is:USBC 9J080440A. Sorry but I know nothing about bowling. I'm trying to help my friend sell this ball that was used only once. Thanks!
Can I tell from the serial number? NO.
1- stop by the local lanes go in the pro shop and have them weight it.
2- if one of the local grocery stores have a public scale use it.
3- use your home scale if it's pretty accurate.
4- go to the post office ask them to weight it.
