The LC brass weighs just about the same as other brand commercial cases, so it's not the heavy military cases that you find laying around at the range.
This means it has about the same case capacity as other commercial cases.
I bought 1000 rounds of LC for $150 at Graf & sons about a month ago on sale.
It does need to be preped like most cases, that is trimmed and the flash hole de burred, but it has done fantastic in my Mini. If you don't like to prep cases, buy Lapua at $20.00 per 50 cases.
Just be aware that a lot of the primer crimped military cases that you find are heavier and have less case capactiy so you should start about 10% lower in the charges in those cases and work up.
Using a max load in a military case could result in having way too high of pressure.
As cheap as the LC 09 cases are, I've stopped bothering with the mil surp cases.
