use 7mm mag as parent case and a 9.3mm/320 grain bullet.

how would that perform?
how would you go about building it?

Probably a hair faster then a 9.3x62 but a bunch more expensive.

Probably pretty well.

I would get to the point you're at, and stop.

A 375 Ruger or 375 H&H would be a lot cheaper.

I don't believe that's a new concept. smile If you go back many years in the Handloader's Digest (I believe); It was called the 9.3 American.

I took a quick perusal, but couldn't lay my fingers on it. IIRC, the author used the .338 Win case but that's rather a moot point...

thts what im hoping to do.the 375 Ruger fits the length and is impressive.It just so happens the 7mm rifle in question has a barrel that was not screwed in,but pressed in. So a rebore is the only option.I dont know if the bbl is thick enough to rebore to .375 or even .366. Any input would be appreciated.

Can a barrel even be re-bored if it can't come off of the receiver?
I would think not, but...

Even better, if you had the knowledge, experience, and wherewithal to develop a "new" wildcat, is this the kind of platform you'd choose?

realitycheck,

What everybody else said already, plus:

I just ran some internal ballistic calculations, and it would get about 100 fps more than the 9.3x62 at the same pressures with 286's.

If you're serious, Charlie Sisk has the reamers for around 20 9.3 wildcats, and I'm sure "your" cartridge is among them.

He wants to build this abortion using a Remington 710 according to his thread in the gunsmithing section.

Sounds like a cluster [bleep] already.

You can't make chit like this up... crazy

So if thats the case, does anyone know how safe it is to have a rifle rebored to lets say from a 7 mm mag to a 9.3x62 Mauser or a .375 Ruger? The cartridge lengths would match and feed properly,but would the barrel be made to thin to run hot loads through it? Has anyone ever had a rifle rebored before? I found a company called JES that rebores rifles to .35+ calibers.

Does anybody have any experience with the Remington model 710 and changing its barrel/caliber?


After getting good advice:

I wont try a Browning though,thanks.
