What is the difference in trajectory between a 7mm 160 gr. AccuBond at 2900 f.p.s and a 7mm 150 gr. Partition at 3025 f.p.s. when both are sighted in at three inches high at 100 yards? I'm curious as to this difference out to 500 yards. Any help would be greatly appreciated.

This data was retrieved from the RCBS Load ballistic program, I assume it is pretty close, I do not know for sure.
This data was using posted Nosler Ballistic Coefficients and calculated for standard atmospheric conditions and sea level elevation.
