Has anyone heard about the Shellshock .308? I've seen some claims that say you get a big boost in velocity without changing the grain weight. Does that actually hold up in the real world? Also, can we count on those rounds to perform when it matters? It would be great to get some insights on this!
 
What's wrong with 308 Win? If you want more, get a magnum cartridge. Lots of wildcats in magnums also.

EDIT: 300 WSM is a good alternative to 308 Win.

EDIT2: I think I see now what it's all about. It appears to use a hybrid case like the 277 Fury that uses a steel base with a brass case, so it must get up to 80,000 psi rather than 62,000 psi that the 308 Win gets.

Been thinking about this cartridge, and the one question I keep coming back to is that if one was to chamber for this cartridge, wouldn't it make more sense to go with the 277 Fury, in the sense that the military appears to be moving to that cartridge. It was the military that pretty much made the 308 what it is today, IMO, as it did with the 223/5.56mm as well...it seems to me that was the driving force behind the 308.

In that sense wouldn't the driving force be behind the 277 Fury?

From the Wikipedia page for 277 Fury:

"The cartridge was designed by SIG Sauer for the United States Army's Next Generation Squad Weapon Program (NGSW). It is dimensionally similar to the 7.62×51mm NATO service cartridge."

That sound like the Shellshock 308 with a slightly smaller caliper. I guess my question is if it would make more sense to go with the smaller projectile, as the military is doing?

That said, I do like the 30 cal projectiles, just that I have solutions for that today with 308/300WM/300WSM. I don't have them in 80,000 psi cases, but do I really need that? Until the hybrid vs the Peak Alloy debate is settled, it seems a crap shoot...What say ye?
