So from what I gather this is custom lathe turned brass with considerable advantages. There is a $250 wildcat set up fee minimum of 100 pieces for a wildcat order or 50 pieces for regular non wildcat order. There is an additional $50 for a head stamp with a custom head stamp of your choosing which is dirt cheap! It is made from hammer forged brass/copper in diameters of 5/8” 7/8” or 1 1/4” It is tested to 65,000 K psi and they will even do a benchrest level quality. Apparently people have used the brass dozens of times without fail. It comes lathe turned with fully formed taper, shoulders and necks. Cost is expensive, but small runs! About $5 a pop for normal stuff to $10 a pop for cases like the mighty T-Rex or say a 12 Gauge or 4 bore capable of 65k PSI. A great option for hard to find stuff or wildcatting on a small scale. This is pretty cool stuff!

Sounds great for a select group on gunnys, of which I can be one from time to time, but it sure makes one's billfold about 2 lbs lighter n a cork..

For what they do, I am actually pretty shocked how cheap it is. It comes to your spec, brass thickness in all the right areas and all. Imagine a one piece 12 GFH @ 65K psi! 577 T-Rex on tap! you could probably get fully formed brass before reamers and dies! Your imagination is the only limit. This seems like science fiction for wildcatting.

Sure does ! Science fiction or magic !
Thanks for posting that.
Somehow I missed out on it but they have been at it since 2018 ?

Somebody there is doing their homework.
The AR.COM gang of wildcatters is well represented.
Robgunbuilder's Biggies, Hubel's Heavies, Jeffeoso's Accurate Reloading Cats, Michael458's B&M and MDM Cats, lots of obscure and obsolete stuff and even lots of common stuff.

They even have 7 of my Stray Cats posted there with prices and "30-06-like" aka nicknames.
Only 5 of the 7 have drawings of headstamp, so far:

.500 Mbogo/50-08 ($6.18 ea.): The .510/470 Mbogo 3-Inch.


12.7x68mm Magnum/49-10 ($5.75 ea.): The .500/.338 Lapua Magnum Improved.


.400 Whelen-Berry ($5.56 ea.): Uses same handloading dies as .400 Whelen of Michael Petrov, with less neck taper, better shoulder, 0.188" longer throat,
can be used for 3.4" or 3.6" COL.


.395 Tatanka/40-07 ($6.05 ea.): .395/.416 Rigby full length, with 20-degree shoulder instead of 45-degree.


.375-404 Jeffery Saeed ($5.95 ea.): As reverse engineered by me from Saeed's wildcat. Handloading dies still available from Hornady Custom.
Safari espionage was involved.


.375 Twister ($5.84): My version of the .375/.338 Lapua Magnum Unimproved, independently developed, though Waffen Jung might have beat me to it.
They called theirs the 9.5mm Tornado, copyrighted so that even the German Air Force has to pay them royalties for use of the "Tornado" name on their jet and weapons systems.
Thus, for giggles I called mine the .375 Twister.
Same handloading dies work for both, from Treibel.
What a coincidence, a God wink.


.264 Ripmoor ($5.67 ea.): A .375 Ruger with a 6.5mm Creedmoor neck and throat. Not just a too-short-necked straight neck-down of a .375 Ruger.
It was born on these forums.


I surely am surprised, and happy to see my cats offered. I have no copyrights.
They are released to the industry.
Will have to budget and pace myself in acquiring the R.C.C. brass.
I'll have to see it to believe such sorcery !

The .500 Mbogo and .395 Tatanka are the only cats I ever had brass made for, by Quality Cartridge.
Those would be the so-called .50-08 and .40-07 to go with my .30-06.

The problem a lot of people have is finding quality brass for the caliber they shoot. We manufacture high quality cartridges for vintage, obsolete, hard to find and wildcat calibers. All cartridges are made to SAAMI, CIP or tolerances provided to us. Our unique process allows us to manufacture over 1,400 different cartridges at tolerances up to 0.0005”. We can manufacture brass cartridges for any firearm, and if you are seeking quality products made in the USA, then you are at the right place.

The draw process has been used for cartridge manufacturing since the 19th century and manufacturers have been able to develop this process to produce high volumes of brass cases. Draw cartridge manufactures have tested many different types of materials over the years and the best material for this process is a brass alloy with a mixture of 70% copper and 30% zinc.

When brass is annealed at 250° C there is no visible change to the bonding of the grain structure, tensile strength and elasticity. At 300° C there is a microscopic change to the grain structure and at 350° the work hardness becomes softer and a fine grain structure can be seen. As temperatures increase the brass becomes fully annealed at 750° C and large crystals can be seen. Temperatures above this point will cause damage to the brass and at 800°C the brass is burned and should be scrapped.

When brass is cold-worked it hardens and done by bending, drawing, compressing and so forth. This increases the tensile strength and decreases it’s elasticity. To accommodate today’s high pressure cartridges brass must both have a high tensile strength to withstand pressure spikes and elasticity to seal the chamber from any gas blow back.

The draw process begins using a brass cup that is annealed and cleaned to remove any scale build up that might have occurred. During the first draw the cup is pushed through a die with a punch and extruded to lengthen the cup. It has become work hardened and has to be annealed and washed for the second draw. Typically a cartridge will go through 4 draws before it is ready to go to the next stage. The case head will be turned, primer pockets, flash holes, head stamps and necks are done to complete the manufacturing process. When the neck is formed the cartridge is annealed again and is then polished for shipping. During each annealing, the temperature is reduced to work harden the case for higher tensile strength and elasticity. The final annealing is to the body of the case and is at a lower temperature, so it won’t affect the case head hardness.

While the draw process is capable of mass production, it is not able to easily produce consistence case head hardness, case weight, case volume and case concentricity. At RCC Brass™ we have taken those variables out of the manufacturing process as we have our C260 cartridge brass hammer forged into a tight molecular grain structure with a high tensile strength and 15% elasticity. We machine all our cases on CNC lathes and mills and our case weight, case volume and our case concentricity are the best available in the industry. We don’t anneal the case head as it is hammer forged to a high tensile strength which gives us the same hardness for each case. Since we are use CNC equipment to manufacture our, case weight is nearly identical, the case volume is too, and our case concentricity is held to a 0.001”.

Since we are not held back by the limitations of a draw system, we are able to use higher strength alloys to manufacture cartridges. Our new C272 brass alloy has a much higher tensile strength and tighter molecular grain structure than C260 brass, without losing the needed elasticity. Test results have been very positive as we’ve had reports of increased in velocity and energy and lower shot deviations versus C260 drawn brass. But the test is what you can do with RCC Brass™.

I see a couple of my kittens
358 Gremlin
400-375 HH AKA 400 Karamojo

Even something I had pondered a long time ago 458-404

A cool thing was the 400-350 Rigby as well as the 350 Rigby

all the Accrel carts

All the Hubel express carts

https://www.rccbrass.com/shop/...duct_cat=center-fire

Go through the list!

550 flanged, 550 express, 500, 470, 458, and 416 Accrel ?

is RCC one of us?

I was wondering why nobody from there posted it here. I talked to the owner yesterday briefly. Someone at least from that company knows about this place.

The exciting thing is that you don’t need an existing case anymore to make a wildcat. You can design a wildcat whole cloth.

R.C.C. surely got my wildcat specs from www.ammoguide.com
(there is a link to R.C.C. at Ammoguide).
Those that R.C.C. cataloged of mine are just what I have put up at Ammoguide. Every one of the seven.
Heck, I have three more .395 wildcats, reamers from Dave Manson (except Lapua from Dave Kiff at PT&G), handloading dies from Hornady, Redding, and CH4D respectively:

.395 Ruger Max
.398 Lapua Magnum
.400/.395 Nitro Express Aboriginal 3-Inch aka 10.03mm X 75R

And a fifth .395 wildcat made by using a .375 H&H reamer and a .395 neck&throat reamer:

.395 H&H

That one is handloaded using .375 H&H and .395 Ruger Max dies.

With the .395 Tatanka that completes the .395 Big Five.

There could have been a sixth.
Gerard Shultz designed a .395 GSC (.395/.375 H&H Improved)
but that project fell through when the .395 McGowen barrels could not be shipped to RSA.

I don't know if I could afford to collect brass from R.C.C. for all five of my .395 wildcats.

Do you see why I have quit wildcatting and am sticking with the .458 WIN for everything ?
I am in recovery, a member of WA, Wildcatters Anonymous, on the 12-step program:
Build 12 rifles chambered for the .458 WIN-V, 3.4", 3.6", 3.8".

I Talked to the owner yesterday. A nice Texan who said he would post here and maybe we can ask some questions. Been daydreaming about the potential of his technology. Imagine a stronger webbing & longer 405 Win... 2 3/4”? One piece strong 12GFH? A new diameter case? Longer case? Higher pressure case? Proprietary case?

It would be great to hear of any lab testing of this astounding, new-tech brass, i.e.,
pressure data with any any loads tested,
common or obscure.
