What is the actual weight range for a 15# ball?
Is it 15# minimum? Or?
I've seen balls listed a 15 lb. range from 14 lb. 12 oz, to 15 lb. 8 oz.
For 16 lb. balls, I've seen as high as 16 lb. 5 oz.
For 14 lbs, I've seen the same range, from 13 lb. 12 oz to 14 lb. 8 oz.
Considering that drilling, fingers and weight holes can remove anything from 1.5 oz to as much as 5 oz., these ranges should result in a reasonable final weight.
Or, was this a trick question?
