For a hunter wanting to shoot a short barrel/suppressed and not reload, then the cartridge has some merit, but a good reloader can load a 7 Saum, 7SS, 280 AI, 7 PRC or 7 RM in a 20 or 22 inch barrel to quite fast velocities, especially when loading 65 to 70K psi (not recommended with cheap brass). From many of the velocities I see shooters posting, there is no way to get such velocities stated unless the PSI is near 70K. All the modern actions will handle over 100K psi, so it is the cartridge case, not the action, which will fail first. The steel has less stretch and can handle a higher PSI than brass, but will for sure be more difficult to load and accuracy might not be as good as with quality Brass cases. The Sig Fury has a unique design in that the back of the case is steel and front 3/4 or so is brass, giving a unique hybrid that might have more merit than an all steel case. I probably would not run out and buy the new 7mm right now, unless you either have too many guns already or will only shoot factory loads for hunting with a suppressed short barrel rifle.
Too many hunters chase velocity, high BC bullets, fads, etc. instead of just hunting properly, knowing their rifle and shooting within reasonable ranges. A 308 is a legit Western hunting round at under 400 yards and before rangefinders, almost all animals were shot under 400 and 500 yards. I remember when I was 15 and thought I had to have a 300 WBY to hunt, but ended up getting a 30-06 due to recoil and ammo availability. I never liked the 308 or 6.5 CM much but now understand that for certain situations and as training rifles, they are tough to beat. Most shooters need to spend more money on ammo and training than on new guns they only shoot 20 to 40 rounds per year. I love long range shooting, but in hunting conditions it takes a lot of skill and wind judging ability to make consistent first round hits. This new 7mm cartridges is not going to significantly improve an inexperienced shooters ability to hit their targets without practice. Long range shooters should always think follow up shots to make sure animals are anchored quickly. It is the single biggest thing I have seen to avoid wounded animals at any range. I know that got off topic, but in summary, the new 7mm will definitely help sell new rifles, suppressors and ammo. Will it revolutionize shooting and hunting, not likely.
