A video with my usual test media, a wet cardboard bale. Unfortunatly the cardboard was not uniformerly wet. The Bale was shot at 100yards (lasered).
The 7x57 with 160 Woodleigh had a muzzle velocity of 2,405 fps
The 7x57 with 154 Hornady Spt Interlock had a muzzle velocity of 2,461 fps
The 7mmRM with 160 Woodleigh had a muzzle velocity of 2,908fps
I recovered the two Woodleigh projectiles.
The left one was fired from the 7mmRM the right one from the 7x57
Neither of these projectiles resemble any I have recovered from game, however the test did replicate my in-field perceptions of the 7mm 160 Woodleighs performance.
Results at 100 yards Impact:
The 7mmRM has the velocity to expand the 160 Woodleigh the largest.
The 154 Hornady Spt is quite a tough projectile and better suited to 7mm Magnums.
The 7x57 achieves best penetration for the 160 Woodleigh with 2nd best expansion of the three projectiles tested.
