[QUOTE="Bart B, post: 650947, member: 5302"] The shape and size of the shoulder and neck will determint the temperature, shape and size of the flame's jet effect going out of the case mouth. Same thing's used in military jet engines to change the shape of the exhaust for different speeds in flight. Check out: [url=http://en.wikipedia.org/wiki/Propelling_nozzle]Propelling nozzle - Wikipedia, the free encyclopedia[/url] for details. I'm reasonably sure that would effect bore erosion in the leade. There's other factors, too, including the details of how one tests for and determines barrel life. And I really don't think "we all" know that. Surely, there's a few (a lot?) that don't know that.
