Having shot Parker Hale Volunteer rifle for many years can tell you, a nipple will wear out VERY QUICKLY with high pressure loads.
When that happens, the point of impact changes rapidly, and group size becomes more like a pattern than a group size.
If you need 3000 feet per second, get a 7mm Remington mag.
