I totaly dissagree the jacketed bullets do not provide enough penetration and the claim that wide meplat flat point hard cast do not provide enough wound channel or "shock" is quite frankly bull ****.
Exit in the rib cage of a 6X7 Bull Elk with a 440 grain at 950 FPS
Hog taken with a WLFN hard cast at a muzzle velocity of 1400 FPS. Notice that the leg is missing as it pulled off while skinning
A Buffalo that I took with a WLFN flat point hard cast blood poured out of the entrance and exit holes
I believe that the write up that you are referring to was by JJ Hack and I disagree with his Annalise. I have also been unable to get him to say what type of hard cast that he saw in use (round nose or narrow meplat) but he does not respond to that question on the enter net as he has posted that write up on a few boards.
I have taken way too many head of game with LFN, WLFN, and other large meplat hard cast bullets to buy into the BS about them being ineffective..
