We just got our latest shipment of Savage parts, and as usual, there was a few mix ups in the parts and we got a few things we didn't order in place of what we did order. Interestingly, we receive something I have never seen before. At first I thought it was a 338 Lapua bolt head, but after putting the calipers on it, it appears to be a .640 bolt face. Does anyone know if Savage ever produced a rifle based on any cartridges that have a .640 rim diameter?

Regards,
Lance
