Another vote for the party that thinks you are WAY over-stressing on this.
There are also some things you can do to the ammo to make it even more long-lasting -- you can seal both the bullet and primer. Most factory ammo has a sealed bullet, some seal the primer as well.
You really, truly do NOT need this kind of protection in handloads, but it's available. I couldn't ever see me doing it.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
