You don't have many questions today, do ya? [:P]

Military ammo is loaded with primers that have "reduced sensitivity", a requirement that is a result of the fact that nearly all military rifles have free-floating firing pins that will dimple the primer when chambered.

The only company that I know of that sells military primers separately is CCI.  Their #34 is a Large Mag military primer, and their #41 is a Small Mag military primer.  The primers are "magnums" because military ammo is typically loaded with ball powder that often requires a bit hotter of a primer to get a consistant powder burn.

Interestingly, two different methods are used to reduce the primer sensitivity.  For the large primers, the cup is made a bit thicker.  For the small primers, the anvil sits a bit deeper, requiring a deeper primer strike.

The primers are staked in place by the arsenal loading machines.  In the US, a round, circumference stake is used, and is visible as a circle just outside the primer hole.  The die is just a concave tip that presses the edges of the primer hole walls in towards the primer.

Other countries use a 3-point stake.

The sealant is applied a little further down the line.  The rounds are flipped around so the case head is up, and the sealant is applied by a machine.  The closest thing to the sealant used would be nail polish that's been thinned to near-water consistantcy.  Midway sells some expensive primer sealant that is really just pre-thinned clear nail polish.

River Valley Ordnance [url]www.rvow.com[/url] sells fully-processed, once-fired LC brass with re-crimped (but not sealed) Winchester or CCI primers.  I'm not aware of anyone making a primer staking tool for reloading (most reloaders don't want staked primers because they make REloading more difficult).  A machine shop should be able to make such a die pretty easily.  You'd want a stout single-stage press.
