I've been talking with friends about it since the 350 Legend was announced...
... But with the popularity of AR style rifles mixed with straight wall cartridges, I'm hoping for a new caliber war. From my 3 minutes of research, and hours of talking trash, it looks like a 6.8 SPC case can be blown out to a straight walled 10mm/.40
So with .450 Bushmaster (.45 extra long) and .350 Legend (9mm extra long), we could have a .40 extra long using 6.8 as the parent case.
From what I've been told, there's the .401 Self Loading from before WW1. It tossed a 200 grain pill around 2000 ftlbs of energy with 1.5" long case at 37,000 psi.
With a 6.8 at around 1.66" long and 55,000 psi, it would assume it's .40 offspring would be a tad above that .401 SL at over 2000ftlbs... Maybe 2300
And with 350 Legend at 1800ftlbs, and .450 Bushmaster at 2700ftlbs, it would slot right in between.
So.... Why would this cartridge be needed? It wouldn't. But it might sell... because why not? I have no skill in machining nor handloading, so I would never be able to "wildcat" it. I just thought I'd post what I've been thinking about while I'm on the commode.
What's a cool name? Maybe .400 Myth. Or 10mm Widsith. Yes, those are rip-offs of Legend and Beuwolf/Grendel because it's a rip-off caliber.
