As long as you have the buttstock leveled up so that the axis of the buttstock is a perfect 90 degrees to the blade, a chopsaw with a new blade, will make a nice clean cut. It worked for me.
I bought a new shotgun and wanted the stock shortened.
The price charged by the importer was $105 + shipping.
Instead, I went to Home Depot and bought a brand new Ryobi chopsaw for $100 and did it myself. The chopsaw has come in handy in the four years hence, for many home projects from cutting trim for doors and windows to cutting clapboards.
If you have everything squared up before you make the cut, you should have no problems.
Maybe make a dry run on a piece of scrap wood first.
