Will .277 Sig Fury/6.8x51mm catch on?

True, but I doubt Winchester was using today's ordnance grade steel with high chrome moly content. In any case I could live with a 264 even if the barrel life were only 1000 rounds. Here for a good time, not here for a long time.

That ordnance grade steel had been around for a long time. It predates WW2 for sure.
I want to say it was first used in the aircraft industry in the late 1920s and rapidly gained applications from there over the next 10 years.
Even made now 264win mag barrels using 4150 are wearing out after 800-900 shots.
300win mag usually only lasts 1,500 shots, but about 99% of people who have a 300win mag shoot less than 2 boxes of ammo per year through their rifle so you don't really hear about them burning out barrels even with a lot of people having one.
There were pictures on here last year, a guy who had a 300 win mag barrel cut open with no rifling for the first 3 inches of the barrel. Some how he got like 3,500 shots on that one.

The steel head isn’t new technology The O’Connor steel head was introduced in 1984.Their ads were in Handloader magazine for years

It all seems very gimmicky to me because I don’t understand the reason for it.

Were there numerous AARs following contact with the enemy that highlighted the inadequacies of our current small arms? If so, I’ve never read about it.

Or, is this an R&D exercise to design weapons better suited for the battlefield of the future? If so, I think they have a lot more work to do.

Or, is it just another example of a government boondoggle. It kinda has the feel to me.

ETA, again, why a brand new cartridge with a specially designed bimetallic case?

To get a 6.8 diameter 135gn projectile above 3,000 FPS?

OK……any common box of 270 WSM hunting loads already does that without all the “fancy” and millions of dollars of development cost.

Yep, boondoggle
