Is there an upgraded spur for the savage x 4.6? I htough i herad of someone saying the are using an old savage slipper. Is it better? What do i need to do it? I have a racer's edge .32 in it with a ribbed pipe and melted the slipper on it. I also have a set of ofna gold springs to put in it. I tried to put them in but the springs didn't line up with the groove on the nut so i quess there is a shine kit for it? What shoes should i be running? What difference will it have between these and the stock ones?
