will we ever see the .277 Sig Fury?

Mauser style, but I'm sure you know what I mean. The 54 presumably was not initially designed to handle a Hornet or .222, but there's a little difference when a factory engineer signs off on it being strong enough.

There's reams of information and debates on various action strengths. Not all created equal, and I'm not saying anything new about it. Guess it's ultimately up the end user to figure it out.

A 30-30 action will take the power of a hopped up 45-70, or .444 Marlin too, but I don't think too many fellas would load a 30-30 to .308 pressures even if they could get bimetal cases for them.

Winchester did though, with the 307 Winchester cartridge in the model 94. It has the same maximum pressure as the 308
 
^Should probably change his sig line if he doesn’t know why the receiver sides look like this lolIMG_8312.png
Can shoot a 308 in the 307 ones if you want and nothing bad will happen
 
Current politics have rendered it an impossible purchase in Canada. It's a military rifle/cartridge. Though it could herald new high pressure hunting and precision actions if time and politics allow. Cheers

Not a new bore size. Just .277 or .270 Winchester calibre. The idea of getting it as a civilian gun is not appealing at all to me. The cases are bimetal so the extreme pressure of 80 000 doesn't cause issues with the brass flowing. The case price will be prohibitive, and make shooting costs ridiculous. Designed to give good performance out of a short 16" barrel, but will have an extremely obnoxious muzzle report with that kind of pressure and short barrel. Ballistic performance can be duplicated with a regular size .270 and common brass that a fella trips all over at the range.

Or if a fella craves more performance, it's easy to do with a .270 Short Mag, or either some kind of steamy 6.5 or 7 magnum.

I also wonder about some of the hidden costs and problems that will come with a new design.

Designed for a short barreled AR, or Sigs version. So a semi auto for civilians and suppressors. Neither of which we can currently have. Under our current laws it makes no sense. Easily half the cartridge and firearm development goes to improvements to the Ar15. Fitting a more useful, potent caliber. All useless to us.

The new calibers mostly duplicate the performance of legacy rounds. Sure they're manufactured with match chambers and tight twist. From a practical view that helps target shooters. Means next to nothing to hunters.

Having just watched Spomer's video. Dropping it to 70k pressure. One of my 270win is a 1885 with a 28" barrel, how about 270 Weatherby?, doubtful theres much gain. Then theres the 6.8 spc, set to be adopted by the US, then it wasnt, sure could happen to the US in the DOGE age. If this is adopted, brass will be available, bullet manufacturers will push and develop the .277 bore, and nimrods will wildcat it from .223 to probably .375. It's interesting, something to watch, wait, and see.
