Good tips above.
Like Yeti said, flatten the bottom of the pad first. I sand them on the disk until flat.
Once screwed onto the gun, I use a sharp scribe to scribe a line in the pad base all around the stock butt. This will come in handy right near the end of fitting.
I put 2 layers of blue masking tape on the stock all around just above the pad to protect it from a slip. Then I rough the pad down in flat sanding cuts while holding the extended angle of the wood. When I get within a 1/16" or so, I start rounding to the contour of the stock until I start nicking the tape. Then I pull ONE LAYER OF the tape and get as close as possible to the contour. Then I pull the pad and finish it up to the scribed line. A little white chalk in the scribe line helps my old eyes. I've also hand sanded with various grits on the last little bit to make the contours smooth.
