Last month I was in South Africa, and shot an Oryx with a .454 Casull, hard cast bullet in 325 gr.
The animal was standing broadside 85 m - maybe a little bit to the left for me.
I hit it in his shoulder. The bullet went through the skin, then it turned to the right and swerved along the body.
Then it found it`s way to the animals throat (under the skin) and followed it up to it`s mouth.
The Oryx was as mentioned - standing a little bit to the left (when I was looking at him)
I mean that the bullet should start to penetrate - regardless of the animals position.
When does an animal stand complete broadside to the hunter?
Anyway I should believe it would be more natural that the bullet swerved to the left than to the right.
How can a bullet act like this?
It was no branches between the Oryx and me.
Last year I shot a Blue Wildebeest at 105 m with the same kind of bullet and it went through the body as nothing.
The bullet:
Lyman 325 grs.
1386 fps. (Ruger Super Redhawk, 7,5)
Accuracy at 100 m/3-shot groups = 9 cm
