So does this mean that Mr. Dobrenski will have to clarify his sig line, with a foot note as to WHICH 7mm Mashburn he is doing the saving?
Dogger, no, not needed....Docbill is right..Art Mashburn found the full length Mashburn case less efficient back then and the shorter case that we are all using to be the more "efficient" of the two.As a result he named our case the 7mm Mashburn Super
The full length case was much like the 7mm/300 Weatherby or STW of today.....of course they both work, and we have more powders today to help them.Both these cases are peas in a pod, both being full length 300H&H cases blown out and necked down.
But even today neither one really shades the 7mm Mashburn Super by very much. The "Super" is the cartridge that Hagel and Page used for their hunting for years,and the case Dober uses also.That it is formed from 300 Win Mag cases today should tell us the case is more intermediate in length, sitting between cases the length of the 7mm Rem Mag and Weatherby mag on the one hand, and the 7mm STW on the other.
If you call RCBS to order dies, this is the one you will wind up with far as I know..
