So, you take your 9.3x64mm, blow it out to maybe .480" at the shoulder, neck to .416" and chamber your favorite '06 pump or lever with it.
I don't know enough about the rem pumps to say if it would work, but it sure would be neat. For that matter, if the feeding and extraction work, neck it to 358 and 308 as well.
Yee-haw.

Remington has done the 35 Whelen in the pump so a 9.3x62 would be easy. Not sure if the 7600 would handle a magnum cartridge, but I believe the BPR would.

Well, call it a semi-magnum. And there's no reason it has to be high-pressure. Maybe a 350g FN going 2500 fps would keep things tame. Let slip three of those in a row and your teeth may have more trouble than the gun!
RereadingJay Turner's old article about rechambering a 7600 into 338-06, I'm thinking strength is not a basic issue, even at 60k. As long as the tenon and/or front ring will allow the increase of .025" without trouble, it's good to go. (BTW, he mentions 3.3" as functional max COL.)
The main point is that you can't really get a .416" into an '06 case. With the 9.3x64 you can easily. You could even go .423" if you really want. I'm thinking 416" 350g NF would be excellent for non-DG big game worldwide.

It would appear that the 760 or 7600 would distribute the bolt thrust better than some of the Mausers that I've set back with the 404 and ultra mag cases. I think fast acting pumps in the larger bores and 404 dia. plus cases is a nifty idea.

It would be prudent in this case , however, if the rifle were designed and built specificly to handle the wee beasties. Nice thought though. roger

I remember a few years ago someone converted a Browning BAR auto into a .416 Rigby.

I heard that too. And heard it came unstrung afterwards. It may just be vicious rumors though.

bar to rigby is impossible

bar to 416 taylor ot 458 winnie has been done

recall, the MAX length of a bar is .05" over 300 winmag OAL

i'll be doing a BLR to 416 taylor this fall


bb, a 350 at 2500 is, again, not possible in an x62... a 286 at 2300 is.

jeffe

x64.

The article I read on the BAR was about the Taylor. I built one of those a couple of years ago. It was one heck of a chuck rifle!

I'm giving some thought to dooing another.

MD

personally from my dark gun loony side I'd love to take a 760, matte the action and the stock and have it done in a 338/06...grins

BB,
my appologees,

in a pumpgun (must be kept under 58k due to stickiness... which is the max pressure on a factory 280 rem).. even the x64, with a 286, tops out at 2550 in that pressure.

a 350 aint gunna make it to 2500... highest weight i could find, just looking, in QL is a woodleigh 320, and it's TOPPED at 2400 in that pressure range

jeffe

Jeffe, one of these days I'm going to fork out for QL. How do you mean the heaviest bullet you could find? There's lots of heavy 416 bullets, surely, in that database.
And I would question the 58k thing since the 7600's have been chambered in '06 and 270 without problem. That's 62k, right?
For fun, try the 9.3x64mm case, necked to .416" and blown out to a .009"/" taper, with a .350" neck. Load a 320-350g bullet into it with a 24" bbl at 60k and see what you get. Anyway, a 320g is still a big bullet around these parts.

Oh, and if this does work, I've been seeing them used for like $350. Wonder if they're as easy to switch barrels as the 760's are. How cool to have a x64mm switch barrel in .308", .358" and .416"! I'm sure the 308 would give the WSM a run for its money.

G'day All, BB, the conversion of 760/7600's to 9.3x62 is quite common here in Australia, usually for deerstalkers chasing Sambar. Don't know how a x64 will work, I would probably try the BPR, given that you can get them as magnums. Should give you more room to work with.
Good luck with your project, let us know how you get on, I might try one myself.
Now, off to get my 760 9.3x62 ready for this afternoons hunt!

Cheers, Dave.
Non Illegitium Carborundum

Gents,

Could the 425 Westley Richards be done in the 760?

Only if shortened and than you would probably have to work out some feed and magazine problems. After all this was done than you would have to cure what looks like a soft brass problem which is exhibited on all the brass I worked with.Once you conquered that you can go on to find out what caused set back in your action.

piece of cake. roger
