Same went for the Pre '64 actions. Factory out of the box was only a starting place. My great grandpa became known for accurizing, bedding, and building custom rifles around the mod 70 and sako actions. He also built beautiful custom mod 12 trap guns, but that's a different discussion. I believe the accurizing included truing the action. To this day, the most accurate rifles I have shot are pre 64 mod 70s or sakos my great grandpa accurized. I also haven't had the opportunity to buy or shoot a true rem 700 custom build.
The 700 is definitely today's standard, but I wonder what it would be like if Winchester didn't stop producing the CRF for all those years?
