What can I use to seal my handloads?

[Skyfire1201]

Call me paranoid, but I want to find something to fully moisture proof my 5.56mm handloads. I'm looking for something that I can brush on (or airbrush if it's thin enough) around the case mouth and primer. I want it to be easy to apply, and clean enough so it doesn't leave crude on the bolt face or throat. Any recommendations?

one designed expressly for reloaders.

i have not used it.

nail polish around the primer pocket.

tar type of sealant at the bullet/case mouth juncture. post it in a second.

pull an m193 round and you'll see something tarry at the base of the bullet.

this may not the be exact same stuff, but it comes close.

I have used George and Roys primer sealant for years.
Markron and Hornady market their brand also.

Careful what you put in the necks or on the bullets. That stuff will be passing through your bore with a great deal of heat and pressure.... so you need to know the chemical and physical reactions of that process.

That said, there's NO need for this. Unless you're doing amphibious operations, standard ammo with no sealant is more than moisture proof.

I live in an area with high humidity, and this is really just for peace of mind. So properly seated primer and crimped bullet should be fine?

I also live in an area of high humidity and would be more concerned with the things Mark mentioned. I just store it in an ammo can with desiccant. Never had a problem.

Can't remark on the others, but the George & Roys sealant is a nitro cellulose base .

This... I'm in a dry climate, but If I weren't, it'd be ammo cans with Desi packs. Ammo REALLY has to be miss-handled to hurt reliability.

I have had a few .223 and 9mm reloads of mine go through the washing machine, and I tried them afterward out of curiosity. Every single one fired. I wouldn't count on that all the time but ammo with no sealant works fine. I have been shooting outside in the pouring rain for hours at a class, and also never had an ammo issue. Unless it was going to be submerged for long periods of time I wouldn't worry about it.

Before you gonza putting nail polish on your stuff, why not test the moisture resistance? I have also gotten handloads, with no sealant, very wet for long periods of time with no ill effects.

There is no easy way to do this, I don't think it is worth the extra effort.

I once tumbled a loaded round in my stainless tumbler for two hours while cleaning some brass. I tore it down and there was no sign of moisture at all in it. Personally I'm not worried enough about it to seal my loads.

Cool, good to know and one less thing for me to worry about.
