[QUOTE="MudRunner2005, post: 1247083, member: 12995"] Actually no, the only one of those factors that improved barrel life is the longer throat. And it's been proven that has a cancelled-affect when you pack the same amount of powder behind the bullet, the flame is going to burn the same amount of time, and just as concentrated (same bore diameter). According to the SAAMI specs, the 7mm STW has a .278" length neck, and the .28 Nosler has a .276" length neck. So, technically, the STW should get you slightly better barrel life... Like I stated in my first post, the ONLY advantage the Nosler has over the STW is the shorter case length to fit in the magazine easier. :cool: As far as cartridge design, yes the Nosler is more of an "improved" design with less wall taper and a sharper angled neck (which I agree in an improvement over the older "positive extraction" design with heavy taper and low shoulder angles) I'll say this again as well...Belted or not makes no difference in how the cartridge performs.
