[QUOTE="elkaholic, post: 2688650, member: 13833"] Most of my cartridges DO have longer necks when I have enough to work with. Take the SS as an example. Besides the 40 degree shoulder, the 7SS has a .331" inch long neck vs a .311 for the saum and about .225" for the wsm. The 7 Mega has a .334" long neck vs the .225" on the wsm, etc. Coupled with the 40 degree shoulder, the flame point is contained more within the case neck instead of directly into the throat. Thats why a 7SS with more capacity, will easily outrun a 6.5/284 and get considerably more barrel life, primarily because of the short neck on the 6.5/284. [/QUOTE]
