Great advice and I really appreciate it. I do not think I am going to need to put in the plywood, as the ridges for the screws are going to fall pretty much in the right place for me to still use them. I am thinking about filling the stock with spray foam, however, once the cut is made. I don't want to fill it and then need to mill it out if I need to make some tweaks.I shorten all my stocks to somewhere between 12.5 and 13 and I'm a six footer, or at least I was before old age shrunk me. I think most factory stocks are too long, and other hunters always seem surprised how my rifles fit them better than their own. As far as shortening synthetic stocks goes I cut them rough within a quarter inch and use a table mounted belt sander to take them to the final length. This lets me keep them square and level for a better fit. I fill the empty stock with spray foam and epoxy a piece of wood in the last three quarter inch to hold the pad screws. It's better to do this before the belt sander finishing so all is flush. It's important to maintain the original pitch. I have found many people seem to want to cut at right angles to the bore and that is not the best.
I do like the idea of cutting within 1/8 or 1/4 and then sanding it down. It seems like that would provide the best finish as well! How big is the belt sander that you use?
