What animals were these recovered from? They look similar to Woodleigh's I have recovered at the range after firing into a Sand/Dirt mix. None of these examples have the smooth,round edge which usually indicates tissue damage. I realize they went through 8 feet of bone however I would still think there would be some evidence of soft tissue penetration. I would enjoy a photo of the animal that took these chunks of lead.

Are you sure of that muzzle energy figure

Here is the math, since you doubted me.



570 gr Woodleigh SP

Chronographed muzzle velocity ~ 2350 fps (minimum)

Bullet mass = 570/7000/32.2/2 = 0.001264418811

Minimum Chronographed Velocity squared = 5522500

Kinetic Energy at the muzzle = 6983 lb-ft. This is the ABSOLUTE minimum muzzle energy that load would produce STATISTICALLY SPEAKING.



Mean Average Chronographed Muzzle Velocity = 2369 fps

Mean Average Chronographed Muzzle Velocity Squared = 5612161

Kinetic Energy at the muzzle = 7096 lb-ft. This is more likely the energy the load developed at the muzzle.



For the 535 gr Woodleigh SP.

Bullet mass = 535/7000/32.2/2 = 0.00118677905945

Minimum Chronographed Muzzle Velocity squared = 5900041

Kinetic Energy at the muzzle = 7002 lb-ft



So Dan, technically speaking I could be exaggerating by 17 lb-ft of muzzle energy when I say the loads ALL had 7000 lb-ft at the muzzle.



The chronograph data represents three 10 shot strings, for each bullet weight, fired over a 6 month time frame. The loads were all from the same lot of IMR4350. They were VERY consistent.



The bullets ALL penetrated some "heavy" bone, actually one slugged it's way through ~ 7" to 8" of bone. That particular bullet is ~ 1/2 gone (missing everything forward of the cannelure except for a "flag" of jacket).



I don't know what to say about these here Woodleigh bullets!



By the way, a hot load generates a muzzle velocity of ~ 2611 fps with the 570 gr Woodleigh. That muzzle energy of 8620 lb-ft!! Could you imagine what that load would do?
