see that mostly in the lighter weights 10-11 lbs. You can draw a line from the pin thru the cg and that is the way the core is laying. What you discribed if you sit the ball with the pin/cg on top the core is sitting straight down if that makes any sence!

 It is my understanding that, if the CG and pin are in the exact same spot, the weightblock was placed "perfectly" in the ball.

 One of the things that creates pin outs (pins away from the cg), are when the weightblock is not "perfectly" centered.

 From what I've been told, having the weightblock off center moves the dynamic center of gravity approximately 1 inch for every 1/8 inch the weightblock is off perfect center.

 To create a ball with a 3-4 inch pin out, the weightblock would need to be around 3/8-1/2 off center.

 If the ball has the cg and the pin in the same spot, it may limit your options some, but there are advanced drilling techniques that can utilize  and maximize the potential of a ball like this.

Did you have the ball weighed to insure the cg was stamped in the correct location.  Could be a 2nd with everything mislabeled.

CG no matter.  Once you drill the ball the center of gravity changes anyway. I have drilled several short pins(less than 1") with CG and pin above finger holes that roll great. Just ignore the CG and drill it unless it is asymetrical,then you need to try to find the MB.

If you don't have a side wt hole in the ball you are missing the best rolling balls out there. Every ball I drill for myself has a side hole,some go deep enough to alter the wt block some don't . All the stuff that i have drilled are legal as I have weighed them out and yes I have had to take out finger wt.
