I have a 722 in 300 Savage and the rear receiver ring is cut for stripper clips. I understand that the 300 Savage was being considered by the military for a sniper round before the .308 was introduced. Does anyone have a rifle like this? I recently sold a 222 Magnum for far more than i ever dreamed possible and learned that the gun was also used as a military prototype. It seems that Remington built some rifles for shipment to Aberdeen Proving Grounds to be tested for replacing the Garand and 30-06. I'm looking for any additional info on the 722 military project if it's out there.
