I went for it with a 1970's Rem. 700 in 7mm that I got from my father. It was finicky when I got it regarding ammo and accuracy in general was not where I wanted it to be.
I started trying different stuff with it to see if I could get it where I wanted it. I swapped stocks, trigger, mounts, and scopes with really no improvement. I did find a slight bulge in the barrel so the easy fix was off the table for me.
Having a useless rifle in the safe (and one with sentimental value) kills me, so I decided to rebarrel. I wasn't concerned with keeping it original so much as using what I was given. I stayed with 7mm but went with a faster twist proof barrel. The stock is now a manners and the trigger was replaced with a trigger tech. Now I have a rifle that I trust and enjoy much more than in its original form. The cost of action work and refinishing gets a guy pretty close to a new action, like a bighorn origin, on sale but I would still have a rifle that I was not confident hunting with sitting around, in my opinion, neglected.
I kept all the original parts if I ever decide I need a wall hanger or Great Outdoors style lamp.
