Sure, I use a sharpe gouge and cut a slight trough in the butt that is very close to the edge. This relief cut allows any high spots on the leather to fit into the trough and gives a tighter fit between the leather covered pad and the butt. I usually have to adjust the cut a bit after my first pass. I install the pad, locate any gaps, then remove the pad enlarge the relief where I have a gap, re-install and check the fit. I hope that helps.
