Does anyone know if a 6.5 rum will push a 140 grain bullet at 3500 fps? What kind of barrel life are we looking at.

With the right twist, bbl leghth, and coated bullets, you can drive the 175, 178 and some 180's at 3500 FPS with the 300 RUM. Why would you ever want to shoot a 140 grain bullet at that speed with the same case?
