What type of material would one use for a flex shaft, to be mounted off the base of a front rest to hold the ammo close to the loading port? I know how i want to make the holder, i just dont know what actual material to buy.. I dont have any idea were i would buy something like this material either? I know i can buy one already made from sinclairs, but heck i could probably build it for a fraction of the price. Some guys use a magnetic indicator holder for theirs. I might like mine to be a little more refined. Any ideas? Lee
