Excellent.
More load data for the Square Table Manual.
No doubt it will have to be self-published.
Heh-heh-heh.

And field tested in Africa on pachyderms in a couple of months.

Jolly good show old man, Sir Khulu.
Take notes and photos on the entrance and
exit holes from those CEB FNs
passing through the elephant.
Another chapter for the Square Table book.

The FN M98 .458 WinMag is feeding well
after the Gunsmith worked his magic.
Waiting for finish work.

How much AA2230 behind the CEB BBW #13 in am Interarm MarkX?

got back from Africa 2 weeks ago so I have to get in gear and post a full report but need to figure out how to post pictures as I am a dork when it comes to doing things on the computer. but 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. this was a plains game hunt with a cow buff on the plate for 3000 but the Safari owner said if we could come up with an old bull broken horn or not wide I could take him for 5000 instead of the normal 8500 he quoted months ago. I did not tape him but I would say he was about 38 inches but the boss was a good 14 plus inches, wide huge bull. we guessed his weight at about 17-1800 pounds and he was very old probably his last year, a great animal. also took Sable, Kudu, Zebra, and 2 huge warthogs was a great trip to the East Cape

Good show!! Looking forward to your photos.

The 404 Grain Hammer bullet is an extremely effective bullet

Sir John,
I use 78.0 grains with the 450-gr CEB FN loaded to COL of 3.360" in 2.490" Hornady brass, F215 primer.
5-yard chrono was 2343 fps for 5-shot average
with st.dev. = 4 fps for those 5 shots, 12 fps ES.
That was in a 24-7/8" barrel at 55*F,
Chimera WinCZeckster.
Corrected to MV = 2365 fps for
G1 BC = 0.190.
Subtract only 15 fps per inch of barrel shortening in the 22" to 25" range.
But of course,
different strokes for different rifles, YMMV.

Sir James,
Send me a PM and I would love to post your pictures in the gallery here.
I have been posting from my phone today,
on the road visiting a friend in ICU.
He is not out of the woods yet so I will be driving 200+ miles again tomorrow, or later today, to spell his wife.
I'll be on the 'puter again after that trip.

I am sending you a PM. Asante sana in advance.

Prayers for your friend sir.

Prayers Sent for your Friend Sir Ron!

Thanks. We are hanging in here, prayers for Pal and his Wife appreciated.

Here is the latest buffalo to be Hammered, for Sir James' comments:













WOW !!!

Super trophies 🏆. The Boss on the Buffalo is impressive

Beautiful trophies ! Really nice Buff !
Sounds like a 400 ish grain mono metal bullet at 2400+ fps works AWESOME ! Especially considering no bullets were recovered !
What optic is on your CZ ?

Amazing animals - the buff is awesome!

that is a leupold VX Patrol 1.5-4 with a variable size red dot called Firedot it worked great for an low priced scope and has been holding up to the recoil of up to 2400 FPS using 450 grain bullets

Lauriston Taxidermy in Port Elizabeth will be doing the mounts on the Sable, Zebra and the Kudu, the Warthogs and the Buff will be Euro mounts

Thank you. I'll look for one.
For years I had a VX 2, 1-4 x20 on my Spruce King. Killed Tons of animals with it. But , the non illuminated reticle screwed me a few times. It finally died and I decided all my scopes would be I r from then on.

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.
