I also have a rack of rifles that came from "the family", however, only one was "given to me first" by my Dad. None of the rest were given to me first by anyone. They were either passed along, purchased used, or purchased for other family members. My family doesn't sell guns within the family, they are passed along. That one "given to me first" by my Dad cannot be replaced as it is a custom sporterized Persian Carbine. In time, it too shall be passed along - to my Grandson. Not first, but as a family heirloom.
Your post makes me think how lucky we are to have Dads wanting to give us a rifle and teach us to use and care for it properly, and who find it important to pass along the Legacy of firearms. Your quest for accuracy taking 18years to fix is similar to mine taking 20years. Yours took a trip to the factory and replacement. Mine, fortunately for me, took a new sizing die for the reloading process. You have a firearm with a tremendous warranty. I will remember this as I shop for my Kids & Grandkids! Better for them to have something from Dad or Grampie that they can get properly fixed with little bother or expense, than a Custom job that could never be replaced.
Mine can't be replaced. You are soooo lucky.
