Beautiful work. The style of stock demands a metal butt plate. You could hedge buy adding mercury reducers if you can stand the extra weight or make them removable.

But for bench work with just about any rifle or especially those with more dunch then a 7RM I use a shooting shirt, jacket or sissy pad as I have had a couple of incidents when I got carried away and shot too much before a big hunt only to develop a flinch. Had to learn this lesson several times but a flinch will quickly undo that last smidgen of accuracy you gained by shooting additional rounds. With rifles of 458 and over I will even use a sand bag as a shoulder pad and shoot standing up if possible.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
