Dad gave me a Win 670 for Christmas ‘75 in 243 Win.
It grouped quite decently with the Hornady 75 gr HP (flat base). I wish I had kept it but I had a hankering for a Ruger 77V in 243. I sold the Win 670 for its new price $130 and bought the Ruger for $200. The Ruger is (I still have it) a Liberty model and it shoots lights out.
If I had kept the Winchester it would have been a quintessential tractor and truck rifle ..... shoulda, coulda kept it!
The trigger on a 670 should be quite tunable.
Enjoy!
