New Case Type (Shell Shock Technologies)

Not an expert here, but I would think the low variation iv velocity is due to the consistent loads inside the case. SD of .93? I would think there are too many variables involved other than the case (powder, primer, bullets, methods) to get a consistent low SD...:confused:
 
RC20- "Sloution looking for a problem"

I'm generally shy about 'Super Duper', 'Breakthrough' or 'Makes Everything Else Obslete' claims...
Time always tells!

I can VIVIDLY remember the exact same quote ("Sloution Looking For A Problem") about everything from sabot shotgun slugs to solid state electronics to electronic fuel injection on cars, and a SLEW of other advancements...

Never seen those cases before, don't know how they will work, and I'm going to let someone else do the testing...
But I'm not king to dismiss them off hand, I've been wrong WAY too many times!
(I thought 'Smart Phones' were going to be a 'Fad')
 
They would have had a good idea if they had used the high nickel stainless for the base because it doesn't need to be sized. The high nickel stainless cylinder (or case wall) needs a harder sizing die with different dimensions than a standard die. They don't say what alloy they use but I would bet it is either 405, 410 or 430 with 410 being the obvious choice although 405 is alloyed with aluminum for better ductility. All of these, if my memory serves me, can be annealed or hardened for specific purposes.
The aluminum base and the joint between the base and cylinder turn me off right there. The aluminum base begins to fatigue with the first shot and continues until failure. There is no way to stop it and the environment with nitrates is very bad for any aluminum alloy.

I'll pass on this one and hope for a better brass case in the future.

That's certainly possible, but I have been reloading for 25+ years and don't ever recall seeing that kind of consistency over 10 shots, but on the other hand; I don't reload for a universal receiver or in laboratory conditions either.

I generally consider +/- 20 fps (of the average velocity) a darn good load, I don't get there often, +/- 50fps may be more realistic.

I do not like the idea an all stainless case or cylinder part of an case erodes slowly my stainless chamber and barrel.
Aluminum cases are soft but I understand they are not reloadable. Nickel I consider to hard as well which leaves us again with the tried and trusted brass.
 
I showed the info about this new "brass" to a friend of mine and he wondered if there is an increase or decrease in risk of case rupture when this new technology is used in chambers that do not fully support the case, i.e. Glock. What do you think?
 
Very good Idea and question.

The manufacturer of course says No risk whatsoever.

But if you think a bit, the riveted Joint part -junction-, is just on that spot were the famous Glock smile would be.

I bet the round get stressed a lot there. Maybe not in the first shot but in the following reloads.
I bet they did not try the case in an Glock, -on purpose-!
