In 1983's Petersen Pubs. Volume 1 Number 1 Big Bore Rifles Jact Lott wrote about his .475 LTD, created long before the .577 Tyrannosaurus nomenclature was a glimmer in Art Alphin's mind, and before the .585 Nyati case turning tricks by Ross Seyfried:

(Quote)

Over 10 years ago I designed an ultimate .475 caliber magnum wildcat for the late Hans Tanner which I call the .475 L.T.D. (Lott-Tanner-Dinosaur) and its story was published in the 1973 Guns & Ammo Annual. It was more of a stunt than anything else, but it was also a deadly, practical elephant/buffalo round which used the .577 Nitro-Express case with the rims turned off and made rimless. It equaled or slightly topped the .475 A&M, but in a slightly shorter, fatter case. Frank Pachmayr made an epic magnum rifle for it on a 1917 Remington-Enfield action and mounted one of his Lo-Swing top mounts on it. This mount and the rifle withstood the horrendous recoil, but I confess that not all those who fired it did! In mitigation, it must be pointed out that the .475 L.T.D. was intended only for Tyrannosaurus Rex, the brontosaurus and related varmints--not coyotes! I do not suggest this caliber as a serious option since making cases is difficult and the the case head is really too big for existing bolt faces.

Nickudu: Do you have the 1973 G&A Annual?

Here at at HA!/DOA we are about to bring out a unique new cartridge based on the .505 Gibbs case, called the .475 Kifaru, and we want to turn over all the rocks.

Examples of game not appropriate for the .475 L.T.D., thanks to fla3006.

Everyone has got to be crazy about something.

Variety is the spice of life.

So here I am in the rarified air of the likes of the .475 LTD: Looking for the 1973 G&A Annual for Jack Lott's story on this oddball wildcat.

Jack was Crazy too.

I like to think that I have something somewhat new in the .475 Kifaru. This will be a slightly shortened .505 Gibbs necked down to .475.

The .475 Kifaru case length will be exactly 3.000" or about 0.15" shorter in the neck than the .505 Gibbs.

This case will be readily formed by necking up the .408 Chey Tac and fireforming, until HA!/DOA gets the properly headstamped brass rolling down the pipeline.

So, if anyone can cuckold me by showing reference to a pre-existing .475/.505 Gibbs wildcat, please do.

This will complete the Big Five of HA!/DOA:

.375 Lapua Chui
.423 Lapua Simba
.458 Lapua Nyati
.475 Gibbs Kifaru
.510 Gibbs Tembo

BTW, the .475 Kifaru is highly recommended for coyote and varmints for off-season practice.

I am getting giddy breathing this high altitude air. Somebody knock me off the Hilltop if you can.

No reebate, no deebate!
HA!/DOA offers only the finest, and we won't rip you off: no "wood upgrades"

.475 Kifaru:

.470 Mbogo performance at .470 Nitro-Express pressure.

Three down and one up in a CZ 550 Magnum, Dakota 76 African, Prechtl Mauser 98 Magnum, etc.

Can a Granite Mountain "Biggie" with a .750" bolt be had with a box big enough for Four down?

Three or four down, whatever, the .475 Kifaru and the .510 Tembo deserve a Granite Mountain if for the bolt diameter alone.

A toast of tembo to Kifaru and Tembo.

Rip- Remember the .585 NYATI was also made from the .577NE. We have the .585,.550,.510 and .475 versions of the .600OK also. The .510/.600OK is a pretty decent 1000 yrd accuracy cartridge.-Rob

Thought I had it, for sure, but can't put my hands on it. May be packed away with ton of other stuff at my son's house .. I'll look there next week. OR, you can grab a copy here:
http://www.biblio.com/details.php?dcx=33967381&src=frg

i have heard the 475 on the 505 gibbs is called the 470 royale...ask bwana-be about that. but i am the least one to want to do any parade raining...the shorter case makes you safe in my book.

i still like the idea of the 550 p.h. (550 bullet on the 505 gibbs) sorry its a disease

jeffe...have you done any more tinkering with the 550-505 idea?

rip...are those names solid now?

can i name the 416-lapua the 416 kiboko (hippo in swahili)
if you dont like that the 416 mamba (crocodile)

both are good...you dont have to put it in your line up...but can be a special order

Yes Rob, that is what my first paragraph refers to with Ross's "case turning tricks" ... Jack was doing it before Ross.

Rob,
Congratulations on your ambitious projects. We here at HA!/DOA will be sticking to the KISS principle and not biting off more than we can chew. Just the Big Five here:
.375 Lapua/Chui
.423 Lapua/Simba
.458 Lapua/Nyati
.475 Gibbs/Kifaru
.510 Gibbs/Tembo.

A palm wine toast to you too.

Nick my Friend,
I thank you very much. I ordered it, and it is supposed to be shipped to me within one week. Hopefully it hasn't sold out by the time they process my order, such a priceless gem.

When I get it, I will find someone with a scanner that works and see about posting it here.

boom stick,
Oops, Sometimer's Disease! Thanks for the correction. I fixed it, and checked to see if my Depends needed changing. Safe!

.475 Royale does sound familiar even in this Sometimer's brain. There is very little new for sure.

Ah, well, mine is going to be basically a .408 CheyTac necked up. A little different.

If you blew all the body taper out of the .505 gibbs and necked it up to .550 then you would have 0.031" step per side at the shoulder, and you might have a tough time getting it to feed and extract, but it sure would grip the chamber well and stretch little and decrease bolt thrust maybe.

.550/.505 Gibbs is a no-brainer: a no-no.

That is why there is a need for the belted .550 Magnum/Express and the unique .600 Overkill belted case.

Sorry, no .416 Hippo/Kiboko or Crocodile/Mamba.
HA!/DOA will offer a switch barrel for standard chamberings in .308 Lapua, .338 Lapua, and .416 Rigby to go with the Chui/Simba/Nyati rifle.

HA!/DOA will also offer switch barrels in the standard .408 CheyTac and .505 Gibbs to go with the Kifaru/Tembo rifle.

That is the HA!/DOA Big Five plus five standards: Hanging Ten. Two rifles ten barrels. Like love and marriage, soup and sandwich, horse and carriage, two hands and ten fingers, two feet and ten toes: Hanging Ten. Some tembo to you too.

its all about branding and promoting...practicly no one has heard of the royale and if you promote the tembo and the kifaru (great names!) thats all people will think about and it wont matter realy...i love the mbogo performance at low velocity...a great marketing tool and practical advantage (although the mbogo rocks!) the kifaru realy has not been done so with the advent of all the new 475 bullets... go for it!!!!!

Hi RIP,
The fun part of all this bigger and badder thing is that some poor sucker has to shoot it. When it runs recoil in the 100 plus ft.lbs it take a seasoned shooter to do it consistently. It is not for the meek or timid. At 130 to 140 ft lbs of recoil the gun doesn't leave the cabinet very often. I think people have to see what 2500 fps with a good bullet in a .458 or larger caliber does with a well placed shot to actually believe it. I'm refering to an autopsy.
Take care,
Dave

Thanks, Dave. You wrote the book on how this is done. I swear I am quitting the wildcats and going hunting with them after this is done: Gig Five, in my dreams.

What I should tell a shrink while lying on the couch:

"It all started for me in 1985 with the .375 Weatherby, then the .416 and .450 Barnes Supreme's.

"Right after I had the .416 Barnes Supreme in my paws, Remington announced they were coming out with the .416 Remington Magnum. Wow! a new one.

"The Barnes Supreme was basically the same thing and it went back to 1949.

"George Hoffman made a name for himself with a re-invention of the wheel.

"I want to take up surfing and Hang Ten with The Big Five ... (theme music to The Twilight Zone starts here) ...

Dave, I think most shooters feel that way about 40 ft lbs of recoil. Much less anything greater. Those of us who CAN shoot rifles of 65 ft lbs and over, without flinching and enjoy them are few and far between. Even fewer when you get to the 100+ range.

Hog Killer

How much recoil does a 458 win/ 500 NE/577NE have in ft lbs?

Here you go, do it yourself.

Recoil Calculator

Have fun.

Hog Killer

when can we expect to see the 475 kifaru used on the iron buffalo?

what is your next project rifle to be finished?

thanks

Thanks. 500NE worked out to 45 ft lbs. Jeez really puts anything over 100 into perspective.

I think you misfigured, it should be in the 70-75 ft lb range.

boom stick,
The .423 Lapua is being done on a Dakota 76 African in homage to Dakota doing the .423 Dakota-Lapua (top secret specs).

The next one will be .475 Kifaru and .510 Tembo (Five-Ten-Tembo) switch barrel on a Granite Mountain Biggie.

The Iron Buffalo has served it's purpose. I have no more questions in that regard. It is out to pasture but could be rounded up anytime for some more fun. The lesson there was: MORE SPEED AND DAMN THE ROUND NOSE SOLIDS!

Pics of the .475 Gibbs/Royale/Kifaru progression to follow.

If I could quit my day job this would be more than hobby fun.

To those that don't "get it" (this wildcat thing):

I would like to know how I can form the following
How I can do them
Of which gauge I can do them Es which it are make from 505 Gibbs or 408 Chenne TAC Where can be of another gauge


427 Kilafu Long Horn
308 Chui
338 Simba
375 Nyati
505 Gibbs Bibi
308 Lapua Chui
338 Lapua Simba

500grains,
The Winds of Havoc have replaced the stupid .475 Gibbs with the smart .470 Mbogo.

For the latest list of monikers for the HA!/DOA Lineup see the ".423 Dakota" thread by newcomer champlin.

Rifles yet to be completed:
.427 Lapua Kifaru
.457 Lakota Boom Stick
.510 Tatanka.

Yes, I have been working on the .427 Lapua Kifaru for well over a year. It all started in 2004 when I visited Dakota to see if they had an action I could buy. "Nope." I finally got one at Brownells. It is back at Dakota to have the burrs on the receiver threads chased out.

tera,
Come now! You can figure this out yourself. See the ".423 Dakota" thread for the latest fun list.
