I am posting this over at the Hammer Bullets forum to let them know.
It is on "The .45-90 a Tale of Two Rifles" thread, hence the kissing up to the .45-90 WCF:Here is the second known cape buffalo taken with the 404-gr/.458 Shock Hammer.
It happened in Late April 2023 in RSA.
Sir James did it, aka Hydehunter, with a CZ 550 Magnum .458 WinMag:
"...here is how the cape buff hunt went with my 458 plus P. 404 gr shock Hammer bullet 80 gr AA2230 for 2460 fps. came across the buff standing looking at me with death on his face at about 20 yards PH said shoot him, put a bullet in the left shoulder that went thru the heart we found out later and he spun and ran about 50 feet and went down, got behind him and put the insurance shot between the shoulders and done. neither bullet was recovered."
Sir James loads the 404-gr long and keeps velocity down and accuracy good in his long magazine box.
At a COL of 3.380" we easily get +2500 fps in 24" barrels with 80 grains of AA-2230 in Hornady/Winchester/Remington/Federal brass cases.
That is crimped on the second PDR trough of the 5 troughs (grooves) and six peaks (bands) in the PDR sinusoidal wave of the 404-grainer.
The .45-90 can be loaded crimped on the third trough for a COL of 3.380" also.
You can even go one more and load to COL of 3.480" with crimp on the fourth trough,
if the throat of your .45-90 allows it.
To leave two or more peaks (bands) inside the case, for bullet alignment/concentricity/accuracy/sufficient tension,
you crimp at the middle of the fourth band for maximum COL
With 2.4" case in .45-90, useful COLs: 3.180", 3.280", 3.380", 3.480"
With 2.5" case in .458 WM, useful COLs: 3.280", 3.380", 3.480", 3.580"
If your throat is like on the .458 WinMag,
The longer COL .45-90 WCF will beat a shorter COL .458 WinMag.
Almost like a .458 WinMag loaded to the same COL as a SAAMI .458 Lott will beat the .458 Lott.
This is possible with the 404-gr Shock Hammer and the SAAMI .458 Lott both loaded to 3.580" in a 3.6" mag box.
Dang, that 404-gr Shock hammer is the perfect bullet.
Two shots, two dead cape buffalo bulls, two different hunters getting very similar results on two different safaris.
Sir Jerry and Sir James, asante sana-sana.
