if I may say you have the wrong bag for that stock,( you probalby know that) get a bag with a 1/2 flat or so to fit the bottom better,
I made one a few years back, the WINGS as I called them were a tad higher from the bottom (about middle I believe or just higher) then the bottom should fit into the bottom between the ears better.
Back then (12 years ago I did not know anybody to make a stock like that and just gluing WINGS did not seem like it may work) ESPECIALLY if attending my first couple of years shooting centerfire BR, I had enough problems just worrying about wind flag designs let alone a new style stock
kept thinking on stocks and finally had a hand in a design that caught on (the J in JTR BR)
