Your gage discrimination is not good enough.
I do deal with parts with +/- .010" parts and we use micrometers which has 0.00005" discrimination. Our Gage R&R is less than 10%.
Look at the minitab results.It is not just about GRR%
-You only have 3 ranges..
-Less than 50% points are out of control in XR chart which means your measurement deviation is high.
