What is the most powerful cartridge with a '06 boltface? Is there a full length '06 boltfaced round with a larger body like the .284 winchester? I think it would be cool to have one....someone has done it I'm sure but I've not been able to find it. Thanks! FNMauser

9.3x62 or 375 Hawk

425 WR.. but that's a freak....rebated rim and all.

Hi, fnmauser
Maybe 9,3x66 SAKO, not a wildcat cartridge but not many of them yet, it`s a sako cartridge as you see, it came on the market about 2 years ago. This one have the same boltface and body diameter as the .30 06 and the 9,3x62 only a bit longer.

Lukas are you sure about the 9.3x66 having the same bolt face as the 30-06? I thought it was a 9.3x64 with a tiny bit longer case?

I`m sure, I now have my second rifle in this caliber, custom buildt on a winchester pre 64 action. The first rifle I have in this caliber was a standard Sako 75 hunter, I got my hands on one of the two first 9,3x66 in Norway about two years ago, and used it on moose in Norway and black-bear in Canada before I sold it and started building a new one in the same caliber.

Well, you can easily MAKE one by shaving only 0.020 off the 9.3X64 rim...it is rebated to start with.

The other candidate is the 338-06 AI which gets close to 4000 FPE in a strong bolt rifle. With a long throat, the 300 gr Woodleigh 338 bullet will do 2400 fps. Whether this is better than a 9.3X62 is pure speculation.

The various Gibbs will give you about as much case capacity as you can easily obtain from an 06 case. It moves the shoulder foward. I have several of my on design using a 40 deg shoulder at the same location as the Gibbs using the longer 280 case.

You can also check at AHR. WWW.hunting-rifles.com They have their own design worked up from them by Ken Howell.

Yes jeffe! but it is the right answer to the question ! Freak or not. roger

And if you really want case capacity- .500 Jeffery fits a standard action bolt face and all, and holds more powder than the .450 Ackley

A gunsmith in NZ is building a nice .450 on a necked down Jeffery case. 500grn bullet at 235fps at 41000psi or a 500grn bullet at 2650 at 60000psi.

Ganyana ,
DOn't mean to be "mr correct it" but the 500 jeffe-ry does not fit a standard boltface..

let's clarify, a standard boltface fits a .473" bolt face. the standard mag boltface is what, .530 ISH... and the weatherby/rigby/500 jeffery is just at .600.. and the gibs is bigger.

a jeffery can and will fit a mauser bolt, just not an unmodified one

Jeffe wins with the 425.

Next, how about the 400 whelen.

Karl.

THIS HAS AN UGLY REBATE TOO

aint that the same thing as the 425 WR, with a german name?

jeffe

ya got me...

have a good weekend

How about the 411 Hawk if you want to use cheap '06 brass, no rebated rim, no belt and around 4,000 ft pds of energy.

Not exactly. The .425 WR runs a bullet of .428 to .435 and delivers 5010ME while the 11.2x72 Schuler has a bullet of .440 and lists a ME of 5300 ft. pounds.
Velocities for both rifles run at that magic number 2400.
The rebate is not ugly at all and after putting it through the mill I am confident my Schuler cycles very smoothly and I would have full confidence with it in the bush.

how much is brass???

someone needs to wildcat a 2.5"ish with a 458, 423, 416, and 375 to work in an 06 rifle and 06 boltface any takers

Headstamped brass is available but it can be made from almost any basic out there by cutting the rebate on the rim.

I think the Hawk lineup and the Gibbs lineup and Zeglin rifles have all pretty much done that haven't they?

Did an 8mm X 2.5 WR. Found out that the available bras from two different manufacturers was too soft and this problem was accsentuated by the rebated bareing surface on the bolt. got extrusion into the ejecter slot at 30/06 energy levels. Charles Huntington concurred that the brass shouldn't be used for wildcatting. roger

I had a set of 11MM mauser dies so I just had to fool with them. I turned the belts off a few 458 cases, and recut the head to 06 size. Run into the 11 MM dies, trimmed, and presto! I had an 11.2x60 shuler. I even have a 2 cavity 385 grn RCBS mold and a .440 sizer. I havent found a .440 dia barrel so my experiment stopped there, looks like a good moose gun though.

That is waaaaayyyy too rebated Boom!! Oh man! Picture it!! A ground hog is charging and you can't cycle the next round cause the bolt slipped over the case head!

I still think this one is simple and effective.
