For simplicity; mauser large ring/small ring term has historically associated with either the small ring size barrel thread diameter of 0.98" or the large ring thread diameter of 1.1"; granted ring sizes are different BUT it is not the rule but the exception as there are large ring + small shank 98s and as such it can get confusing. As I said, at least when I use the term large ring mauser I'm referring to large barrel shank.
With the weatherby 378 case - as a result of the finer/shallower savage threads there is more 'meat' left on the barrel after chambering a small 'shank' savage compared to all other commercial actions whether Rem, Mauser large and even Weatherby itself. 378 case on either small or large Savage is ok in my book...
