GunDoc,
I don't know just what measurement you are looking for here, as I don't know what the term "bolt cut" means. However, I measured the length of the ejection ports on a pair of 70 Classics I have hanging around the premises. On a Classic Stainless .338WM (standard magnum action) the ejection port measures 3.118". A Classic Stainless .300 Weatherby Mag (full-length magnum or express action) the ejection port measures 3.373". The express action has the front of the rear bridge relieved to allow the longer ejection port, and as a consequence has the .330" scope base screw spacing. No ejection problems on any of my Classics, but then mine haven't been modified. Hope this helps.
