[QUOTE="112Savage, post: 667282, member: 38801"] we are slightly detracting from the OP's decision to be made, but coincidentally there is a similar threat propagating on Accurateshooter.com talking about neck length and erosion. Using similar math to that used in the following article and high school trigonometry classes. [url=http://www.reloadersnest.com/article_shoulder_angle_oct2603.asp]Is there magic in a case's shoulder angle relative to its neck length? @ www.reloadersnest.com[/url] The 264 WM has a turbulence point 109% the length of the neck which is significantly less than the 223 remington 130%, 308 winchester 139%, 30-06 springfield 129% or the 300 winchester magnum 125%. Personally having owned a 223, 25-06, 264wm, and 308 throat erosion may be slightly determined by the turbulence point but more so by the heat/pressure and dwell time of that heat and pressure. I think its bull hockey to believe that tangental abrasion of the throat by burning powder is the primary factor to blame for worn out lands. [/QUOTE]
