Is case-neck sealant necessary, or is it just military dogma done for the sake of tradition and "That's how it's done!"?

I understand how sealed primers matter, but sealed case-necks? Doesn't neck tension against projectile accomplish sealing?

I guess it depends on where you store them and shoot them. If under water then YES it is needed.

I have loaded thousands of rounds and never done the neck or primers, never had an issue and some of my stuff is from the late 80's that i loaded.

Not needed.

Is it necessary to hold the projectile in place - no. However a water immersion test is required to meet most military specifications - and without sealant, not many rounds would pass.

One way to answer is that if you want to meet the spec, you follow those requirements and most mil-spec ammo requires sealant as well as having neck tension force requirements that reflect the sealants.

Another way to answer is when there is a clean sheet of paper out, which doesn't happen very often, would we have skipped the sealant? Probably not for bulk mil-spec ammo for small arms.

In a few cases where weapon systems are known to have very clean conditions, one could ponder skipping it. That (skipping it) almost never comes up when we are talking about the wild variety of storage conditions and logistics that come up.
