Bob, I haven't had nearly as many M 70s as you so I understand the %.
All of my 70s are/have been XTR or later NH. My Black Shadow I don't think is an XTR.
I have had great accuracy from every one. I mean 1" or less with handloads. Once I get any rifle shooting 1" or so, I don't look for 'target' accuracy.
Also I count myself very lucky.... with 70s AND 700s I have not had ONE of the 'common'(?) problems.

Jerry I have had excellent accuracy from ALL of them; pre 64, Classic, and BACO. Enough so that I will never pick a clear winner. The pre 64 is as good as any of them, including those made today.
I have not owned enough BACO rifles to say they function better over all than a pre 64, of which I have owned.....well.....quite a few.
I have seen more Classics and PF's have problems with function than any sampling of pre 64's.
