yeah - apologies for the confusion
I couldn't think of a proper term in english for these things.
But your description describes exactly what we have here.
As to longevity of the cases:
the maker recommends as follows:
a) do not use excessive loads to avoid bulging of the cartridge case
b) do not use an expander die on the neck, but neck-size outside only
c) warm up the neck of a cartridge for 5 seconds with a 'soft' gas flame after each 5 shots (without bringing it to a glow)
in order to retain elasticity.
he reckons that the cases will actually last quite a long time (without giving a figure of course...)
I personally would also not put a crimp on the bullet.
I have bought a batch of 10 in .222 Rem - if I start using just one of the cases and try to load this, say, 25 times, I should find out in a few weeks time what state it is in after 25 loads.
Best regards
Günter
