That's a 1950's 99R, fairly common in 300 Savage. Known for being heavy, but with a good rep for being very accurate. Nice setup and very nice condition. You could probably watch gunbroker and see how much similar ones sell for. Being that it's a 300 Savage it's not going to make anybody rich. But since it was your uncle's, keep the thing in the family and pass it along.
