Pre 64 Win 70 barrels up to 1952 are the cream of the crop. These all had integral front ramps, were beautifully lapped and chambered with between 5 and 7 reamers, depending on the caliber. After 1952 the shortcuts started. Internally they were still good up to 1955 in all calibers, with rarer calibers good up til the end as they were olde stock for the most part. Even with the shortcuts, they still shoot great. I have two very late Fwt barrels that are sub-MOA for three shots, actually cloverleaf or less.
I think the only barrel as capable as a pre 64 Win 70 would be Krieger. I am talking great hunting rifle accuracy and longlife.
