About 4 or 5 years ago I put some loved old pills in a non tempature controlled storage bin.  In the middle of the country!  Extremes both up and down!

About 1/8 have cracked in half!  The other half I've slowly recaptured.

Recently took two beloved out.  A Hammer 3D Violet once 15.0 pre drill.  The other a Hammer Sledgehammer once 15.3 at drill.

Now I'm throwing them well and loving the reaction.  Surprise the old Violet is now down to lean and light 14 pounds!  The huskier Sledghammer weighs in at 14 pounds 9 ounces!!

Are you kidding me?  Can one put their balls on a diet?

PS I AM aware that many drillings take out about 2 ounces of material or slightly more if a weighthole?

Hey Lucky,

I had over 20 crack in the shop from sitting (all brands) over the years. My temperature range in the shop was no less then 40 to high 90's fahrenheit (entirely carpeted as well). The only common denominator I could figure out between all of them was that I physically did not touch them or move them, shortest time period for me was 5 weeks.  I had over 70 staff balls at one time along with 40-50 in the used ball area so there was a fair amount of stuff in there.  I even had some crack sitting on a ball rack 3ft up from the ground. 

I saw certain batches from a manufacturer that had problems but simply had others just crack all the way around the ball.  Not until I started learning more about ball design and actually how they were produced did I learn and understand what Juggernaut has stated about the curing process. 

I never tested them for difference in weight though, just discarded them.
