They patented, what? An alloy case? Hard for me to see that sticking. All Hornady has to do is ever so slightly tweak the alloy and that would circumvent the patent. I’m not a patent lawyer…

Guessing if its patented there are several different ones, likely focused on multiple facets of the project that have presnented design hurdles in the past, but I would imagine stuff like the particular way they fix the primer into the case, so it doesn’t blow out under such high pressure, maybe some of the processes in manufacturing, I don’t know. But steel cases have been in use for a long time, so I agree it’s not likely something simple, it’ll be something very specific around how they solved a particular problem, that might make it difficult for another company to replicate what they’re doing.

Folks are asking about reloading. With standard cartridges primers are one of the key indicators of excessive pressure. Im not a reloader so I dont know details, but Im curious what prevents the higher pressure in these cases to not blow out primers? Do they require a different type of primer? What pressure signs will folks use to tell where they hit 85k psi (or whatever) in these new cases? I imagine there’s a way, but seems like it may require a new learning curve?

You're right, there will definitely be a learning curve. Traditional pressure signs like reading primers are notoriously inaccurate so they can't really be relied on currently let alone converting them over to new high pressure tech.

The way to keep things on the rails is to use a chronograph, in conjunction with pressure tested data in a load manual if possible.

In my admittedly limited understanding of SAAMI rules and regulations, I thought anything approved by SAAMI can be freely used by all SAAMI members.
