[QUOTE="Trickymissfit, post: 708306, member: 25383"] Looking at the case drawings of the 7STW and a couple others, and also the amount of powder they go thru (powder's not getting cheaper by the way). I think a guy would be smart to make the same basic case with a 35 degree shoulder and and push the shoulder back about .100". I doubt you'd ever see the difference in velocity, but I also think you;d see a honest 1500 round barrel life out of a medium weight barrel. This is kind of what Mashburn did with his long 7mm mag. Now I know that the word "overbore" is a touchey subject around here, but suggest you read what Ackley had to say about his own 7mm mag. Basicly he said it was an overbore case, and also said why bother when you have the 7mm Remington mag on the shelf! Ackley was a fan of the Mashburn super short magnum, and felt the Weatherby was the best of the bigger capacity mags. Had the STW used a 35 degree shoulder with a "real" .35" neck length the barrels would have lasted much longer. gary [/QUOTE]
