Woodleigh 7mm 160 grain Penetration Test


Active Member
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.

No way :scared:. Disconnected the truck and drove it off. The bale weighs too much to lift when wet but it will be on the ground when I test 175's from both 7mm rifles. I know the 154 Hornady has a great rep with yanks as an Elk bullet but I couldn't find it.

Just goes to show that the old African hands knew what they talked about when they said the perfect muzzle velocity for penetration is about 2400-2450 fps.
