billebob Most bullet manufactures list the same loads for their round nose and spitzer bullets of the the same weight. Assuming the bullet jackets are drawn from the same material and are the same hardness and are the same weight the only other thing that would affect the pressure is the bearing surface of the bullet.Boat tail bullets can often be driven to slightly higher velocities for that reason but there is very little difference between most pointed and round nose bullets of the same manufacturer.
With the exception of the now discontinued 105gr speer 243 RN all the printed loading data I have seen treats spitzers and RN as the same. The extra pressure that might result from the bearing surface could be negated by the shorter bullet increasing available case capacity.
Someone ran quickload for me for my 9.3x62, the woodleigh being a RN allowed an amount more powder and hence velocity for the same pressures, of course being a RN the increased velocity would soon have bled off.
I am really impressed with the Hornady RN in my 7x57.
