This rifle was owned by my late father-in-law as a bone stock R700 BDL 7RM and we hunted together for 25 years. He never shot anything with it. When he was in hospice about a week before he passed away, he asked me to rebuild it like some of my other rifles and kill an elk for him. A week after he passed away, I dropped it off at the GS and had it built. That fall, my younger daughter was the forst person to kill anything with it. A cow elk. I killed my biggest bull to date the following year. My older daughter killed her last elk with it. It is now the go-to family rifle for extended family members to use for elk hunting. Cousins, nephews, my brother, my son-in-law, etc. It has many killed elk from 50ish to 881 yds.
It is 100% the ONLY rifle I would never get rid of until I hand it down. I could sell all my other guns and not shed a tear, but not that one. That is a legacy rifle.
