[QUOTE="Deleted member 46119, post: 955691"] I just checked QuickDesign for some numbers to compare to the 7STW. The 3 things I think are significant to compare are shoulder angle, neck length and of course capacity. The shoulder angle of the STW is ~25degrees and the Nosler is like the RUM, WSM, RSAUM, Dakota, Ruger and other 404 Jefferies based designs at ~35degrees. In neck length the STW has IHMO the edge at ~.333 compared to the 284/26 Nosler's ~.273 Case capacity, per QuickDesign, is very close at ~100 for the STW vs. ~104 for the 284/26 Nosler. Of course these are not the real numbers so I consider then so close as to be the same. My feelings on this. With case capacity so close any differences come down to shoulder angle and neck length and how the charge reacts to the pressure shaping from the those. On the STW as I understand it, the longer powder column and narrower shoulder angle should shape the pressure wave well and help erosion. With the Nosler like other 35 degree shoulders the shaping of the pressure wave is different but of course actual use shows us that it works very well. As far as I can determine the only actual differences are going to be belted or not and magazine length for shallow seated bullets like VLDs. [/QUOTE]
