bump for some nice rifles, wish I had some spare change
FYI - Urban legend about the heart stamp / Hart barrel myth .....
based on my rifle building knowledge and association with benchrest shooters and barrel makers, Hart never made barrels for Remington.
Mike Walker was the head guru at Remington and had control over new cartridge designs and making accurate rifles. Mike created the Remington 721, 722, and 700 series of rifles along with the triple duece.
Mike was very close friends with Clyde Hart, and consulted with Clyde on a new barrel - rifling process. Walker invented the button rifling process and shared his design with Hart.
In the mid 1960's, Remington made quality stainless barrels that were as good as Hart barrels. These barrels were chambered in 222 and 222 Mag and threaded onto 40X actions.
your rifle barrel has roll marks or a "gallery stamp" done at the factory by one of the employees who assembled the barreled action. The heart stamp does not signify it's a Hart barrel.
the stampings on the right side of the barrel will likely have a triangle with the number or letter inside, next to the letters REP in a circle, next to an upside down heart.
the rifle date of manufacture is determined by the serial number.
It is true that older Remington rifles from 1960 to 1975 shot better (more accurate) due to better QC and hand selection of stocks, actions, and barrels. More recent guns were mass produced with less emphasis on QC.
This is why people who build custom rifles prefer an older 700 action. Much tighter tolerances and everything is trued/machined precisely.
and now you've heard it ....... the rest of the story
regardless of the barrel "stamp" that 6mm should shoot tiny bugholes as I once owned the same vintage gun/caliber
.
