There was a better article done years ago in Gun Digest IIRC bt John Wooters about bullet expansion, killing , and such.
HIS test medium was animals - LIVE animals.
The fact remains ( and the writer of this article admits it himself) that you don't need a premium bullet to lkill game.
They look pretty after you recover them out of test medium, but the TRUE test of a bullet is after you dig it out of the animal you have killed with it.
I used to have more than a few non premium bullets kicking around that were taken from animals that look as good as some of those premiums in the article.
These were one shot kills.
This writer is doing nothing but selling a magazine article, and personally I wouldn't give that gold digger the time of day after the stunt he pulled with the short mag B.S. claiming they were "his" invention!
P.O.Ackley made the same thing years ago with a 348 Winchester necked down to .264 with the rim turned down and made beltless.
