I suppose one way would be to drill three adjacent large holes deep into the butt end of the stock and then chisel out the webs in between so that you have a deep hollowed out area. Then when you drill the hole for the through bolt it won't have to be a really long hole that would be more subject to error. I think Ithaca used that idea on their Nitro Specials.
