8mm (or .30) Super Carry?

It appears that the major ammuniton companies are going to make cartridges for it.

The naming, either .30 or 8mm Super Carry, is a smart idea. No gun company wants to make guns for a cartridge designation that bears a competitor's name.

It's going to be interesting to see the reports once the non-shill press and reviewers get their hands on the gun. I think that it is fair to observe that the revolver equivalents, the .32 H&R Magnum and the .327 Federal Magnum were not huge commercial successes. Introducing a new cartridge at a time when even common cartridges have become hard to find at times seems a little unorthodox. The ballistics tests are kind of marginal and the pressure (50 KPSI) is likely to result in quite a bit of muzzle blast. A .327 Federal has a chamber pressure of 45 KPSI and nobody has ever said that was a quiet round.

This may be a cartridge for places where military camberings are forbidden for civilian use and there may be a market for a reasonably effective handgun cartridge. But it's more likely, in my uninformed opinion, that this will go the way of the .356 TSW.

ETA: Another view of this cartridge, a bit harsher than mine. And what you might expect from the gun press.
