The latest and greatest. Interesting comments about reloading this new fancy case with its special metallurgy. Makes the 223 look puny. LOL.

Well it seemed a pretty honest review, warts and all. If you were someone that wants a pretty cranky cartridge and doesn't reload then it would be pretty good.
Picture hunters buying a 7mm rem mag back in the 60s and shooting 2 or 3 deer a year. One packet would last sighting in and 5 years of hunting
That article was interesting and very well reseached/written, the combined marketing with rifle manufacturers will be the key to its commercial sucess I'd say
The 7prc, 7BC etc comes along and all of a sudden you can hunt with a long action again.
270 is a harmonic divisor number[1]
270 is the fourth number that is divisible by its average integer divisor[2]
270 is a practical number, by the second definition
The sum of the coprime counts for the first 29 integers is 270
270 is a sparsely totient number, the largest integer with 72 as its totient
Given 6 elements, there are 270 square permutations[3]
10! has 270 divisors
270 is the smallest positive integer that has divisors ending by digits 1, 2, …, 9.
Lots of questions on that, no real answers as yet. Would be interesting to note what the case alloy actually is, and how it responds to things like temperature and corrosion. That's a lot of horsepower right next to your face, and it's an interesting concept. Deliberately taking a rifle past it's designed maximum chamber pressure with a set technology and into the danger zone, by substituting materials in the consumable bit.
I would suspect that there won't be many people to be lining up to rechamber an existing rifle in the caliber that's for sure.
Not sure I'm a fan of the steel case tech, as steel cases are not reloadable at the home user level. The material is not easy to work with and for the standard reloading equipment you can't swage it (resize) to get the case to successfully grip the next bullet. Someone will work out a way to reuse another caliber brass case to reduce the costs of shooting the new chambering at a lower performance level 'backwards improving' it!
Funny that. Ive always hunted with one. Unless I put it on the scales I cant really notice the weight difference that every one is so hung up on
An interesting and informative review. The possible problems with handloading will be a turn off for some and the primary extraction problems may need some tinkering with the rifles to solve. Still the cartridge appears to do what is claimed, same performance in a smaller package, so it will be interesting to follow progress.
80,000 psi is not a huge amount greater than some hot rod handloaders are running in selected cases now.

I’d be happy to roll up 140 to 162 gn loads in brass cases at .280 velocities for target snd bread and butter meat hunting. Having the option of buying a 100 full speed 175s For when I had a specific need is a good thing. But saying this if you already have a big 7 or .300 in the safe I’m not likely to buy in yet.
I think this tech will be more interesting to me when it trickles down into the smaller cases I shoot from .223 to .30/06 and may result in a fast twist barrel change when it does.

So.. have pondered this before. If you took a Remington 7 mm mag and extended the fat belt right up to shoulder and left everything else the same,my pondering is that you will have created a very strong case who's body won't stretch.... For sure eventually the shoulder n neck or primer pocket will give out... But a thick walked brass case would be reloadable and could maybe handle higher pressures...this looks to have done same thing by using steel not brass case.... How hot can the steel cases used in Barnaul etc loads be safely used now??? They already in three popular cartridge sizes.
75/15/10 black powder matters
An interesting development that could have multiple good outcomes such as the higher performance noted, the lower cost of steel over brass, and cheaper projectiles as the copper price drops due to the reduced use of brass. The downside is rust with long-term or poor storage, and possible damaged rifles and shooters who seek to overcome the hard bolt lift by lubricating the cases, thereby increasing rearward thrust. Three lug bolts with slightly angled mating surfaces (some rifles have that now) and redesigned primary extraction cams should improve the bolt lift. I can see a good future for this case, especially with the military, although brass will remain mandatory for many lower pressure cartridges to ensure breech sealing.
A thick-walled brass case is still limited by the ultimate strength of brass which is much lower than steel, and pressures will increase in the reduced capacity case. The Barnaul and other steel case brands use a soft steel that is a bit stronger than brass but not a lot. This new steel is in another class altogether.
