My PAP is 4 11/16 Right and 1/2 Up.
My question is on a 15 lbs 3-piece bowling ball (where the CG is on the same spot as the Pin or very close), Is it possible to drill it with Pin 6 inches from PAP which will put the Pin and CG somewhere above the middle finger and still be legal within 1 ounce finger weight? Of course with the help of 1 1/4 balance hole if necessary.

Thanks for the input

Scout Reactive or Storm Mix. I ask local driller and he told me that it will be over the limit on finger weight. I am trying to use the ball for dry lane condition.

Agree with the above statement. I just laid out a ball for myself with my favorite layout of pin 5 inches from pap above middle finger cg stacked negative. longer pins place the cg in my palm. this particular ball was a 1" pin weaker 2 piece ball. Still was able to drill the middle finger deep enough and ring finger/thumb shallow enough to get it within static weight limits.

There is "normal" or average purpose to putting the pin that far on a what is already a very high RG ball with a very tiny differential.  It's a waste of the driller's talent and a waste of your time and worry about almost nothing. See Impending Doom's comments.
