My Dad (1922-2004) hunted with his 300 Savage for many decades. He toppled elk, mule deer, antelope in the western states and deer and bear in Pennsylvania. He also took down a big moose in Ontario, Canada. None got away. The 300 is an excellent cartridge for the modern big game hunter.
Your rifle displays amazing craftsmanship. My guess to value is approx. $625.00.
Fire up the grill! Deer hunting IS NOT catch and release.
