For those who love their .270's, it's time to up your game!

.277 SIG Fury 140 gr. bullet, 3,000 fps, 16" barrel, 80,000psi

Google it.

 

[Rman]

May even be able to neck the .277 suck out of it, to .284?

R.

 

[Suther]

Oh yeah. Load that #### up in Europe at 80k psi, I'm sure it'll do just fine in the deserts of the middle east...

It's a novel idea, and I could see it having applications sometime in the future, but those cases must be expensive (with their 3 piece design and steel case head) and besides, my 270win already does 3000fps with far less pressure. Pass.

That is crazy but I will keep my T3 light in 270 wsm

How original.

3 piece case
Expensive case
277
80000psi (whats a 700 rated for)
Case separation at the joint from work hardening

Barrel wear throat erosion

Oh ya itll catch on lol

Its only hope is a military contract for belt fed guns fed on tax payers dime
Im all for extreme performance but this is a non starter in the civi market

 

[todbartell]

I hope it's primed by Remington's Etronix

Here is a good article discussing this, answers most of the questions. I probably won't be getting one but I would love to shoot one. Developments like this are always interesting.

A .270 WSM matches or exceeds that spec, at 20kpsi less pressure.

What would it do for me that the 284 Winchester wouldn't beside lighted my wallet and ugly up my gun?

A .270 WSM matches or exceeds that spec, at 20kpsi less pressure.

I wonder what a 270 WSM with a 16" barrel would clock for velocity?

Other than firing some, I don't know much about belt fed machine guns. I wouldn't be surprised if the case shape of the WSM would be troublesome to work on a belt fed, there may be a specific length to case diameter required to properly fit the links.

I'll follow this closely. If the commercial equivalent is just as good (I have my doubt but one can hope.), it might be my next cartridge and firearm. Over 3000 FPS in a 16'' barrel sounds awesome!

With that cartridge and barrel length, there will be a lot of muzzle jump.

According to Quickload, under 2,800 FPS with a 140 Sierra and every IMR and Hodgdon power I tried.

Sig say they are going to come out with other cartridges, it will be interesting to see what they come out with.

I expect it to be a real kicker but that's what a muzzle break is for

 

[SuperCub]

This is the only way to improve on the 270.

 

[brybenn]

With that cartridge and barrel length, there will be a lot of muzzle jump.

And likely a blinding muzzle flash to

The 454 casull fella did this along time ago.
