I am considering using a boyds tacticool stock on my upcoming .22 build. However the action is slightly modified so the standard stock won't exactly work. So my question is if I were to buy an unfinished stock for the Savage MKII models if there a filler that I could fill in the action screw holes and magazine and trigger inlets with, and then re-inlet for my action? Any ideas would be appreciated! Seems like Chad Dixon does this with his stocks. I was thinking maybe fiberglass resin thickened with saw dust or some kind of auto body filler such as bondo? Thanks guys!
