Nothing is more dense at high velocity that fluid. Close up, at high velocities this is representative of performance. At slower velocity (within a given window high/low) weight retention performance is increased. Simple ballistics. At the velocity you appear to be shooting a much hardier bullet may be more beneficial, such as an all copper.Opinion. Attached is a photo of two 7mm / 175 ELDX's that were recovered from a 340lb (no kidding) Colorado Mule Deer last year, shot at 383 yards. MZL velocity was 3192 FPS.
They both represent about a 45% weight retention. Is this the performance you would have expected from a hunting bullet?
