Here's one... Not sure about your firing pin though.

"
Firing PinsSavage rifles have two different diameter firing pins.The standard caliber firing pins are .145", the Magnum calibers are .095". These measurements are taken on the part of the firing pin that goes thru the cross pin.All rifles made since 2001 have .095" diameter firing pins. The bolt heads are different for each of the pin diameters.

If you started off with a magnum rifle that has the magnum size firing pin, from the looks of it you should be good to go with this bolt head.
