Thread: Woodleigh 7mm 160 grain Penetration Test

    Woodleigh 7mm 160 grain Penetration Test

    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.

    very interesting
    did you shoot the bale in the trailer whilst hooked up to the truck?!

    No way . 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.
