[QUOTE="Fiftydriver, post: 865692, member: 10"] 2100 yards is some serious range for sure, good shooting! I was also a bit curious about your velocities, they seem really low. In a standard 338 Edge, in a 30" barrel, most often you will see average velocities in the 2850 fps range pretty comfortably, some will easily push 2900 fps if your alright with dropping case life by a couple firings on each case. Now, the improved version of the 338 Edge will not gain a lot in performance. The RUM case is pretty well improved as is, sharpening the shoulder angle will not offer much as far as case capacity increase. What it can do is control case stretching better with top pressure loads but you may also see some extraction issues at very top end pressures as well. As long as your case body taper is more then around 11 thou per inch, you should have no problems, less then this and you will probably see some sticky extraction with the chamber getting a bit dirty. The velocity you were thinking you were getting with your old chrono seems more realistic then the 2780 fps your getting now. That said, a 97.5 gr load seems pretty high as well. In the end, what are your trajectories telling you your velocity is at? What numbers did you need to use to get on target with your drops at 2100 yards? That will mean more then anything. Good shooting!!! [/QUOTE]
