Never sealed a primer but as above I hear fingernail polish works just as well. Buy some cheap stuff. Paint it on and wipe off so it's just in the groove.
No reason to seal them unless maybe some hunting loads that may be exposed to rain or snow Unless you are a "prepper" and plan on burying them
I have had loads without sealed primers that have been submerged in water, more than once. I came home one day and found a bunch of my reloads, high powered rifle stuff, handgun loads, and a huge stash of shot gun shells. All had been completely submerged in water for hours. I dried them up and put them into new ammo boxes. Some didn't get used for a good year or two, and all went bang.
Never "sealed" even one primer.
Before you go to all that trouble to seal primers, you could load a half-dozen rounds and throw them in a pan of water for a day. Take them to the range and test them.
I hope nail polish isnt the "gateway" makeup. If so, you all will be moving on to the hard stuff next! Mascara, blush, lip gloss....so it goes.
So? You gave a problem with that? It matches my outfits!
However, I DO find color-identification of some rounds to be a valuable idea. I load several different "levels" of load in .44 Magnum brass. The first uses a clearly-different 200-grain bullet. The other two use the same bullet, the RCBS 250KT.
The hotter load gets "hot" colors...red, yellow, pink, orange.
The "cooler" load gets cooler colors.... blue, green, black etc.
I use a model-paints kit from Walmart. A single bead of paint from a toothpick will run all around the primer, and after the paint has had time to set-up a bit a wipe with a solvent-dampened cloth will clean up the appearance nicely. (This works best with all the rounds held bullet-down in a cartridge box.)
This paint treatment also has the side effect of sealing the primers...even if it IS un-needed.
Sealing primers on reloads is a waste of time & money.
I started reloading in 1962.
And have hunted in every kind of wet you can imagine.
I have even fished reloaded shotgun shells out of the bottom of a flooded duck blind at the end of the season, and they all fired just fine.
When hunting in monsoon rail, I keep my extra ammo in plastic ammo boxes or a zip-lock bag anyway.
(Unless you are a Navy SEAL, and plan to have to swim three miles, 60' under water to reach your objective on the beach.)
In that case?
The Navy will issue you sealed & waterproof mil-spec ammo to swim ashore with.
I went thru a stage where I sealed everything after a "phizt" instead of a bang on a rattlesnake in a Georgia rain with factory ammo. Tapered off to only sealing hunting rounds. Now I do not seal anything. If I knew I was going into a wet invironment for a hunt I would seal enough for the hunt. It's not like it takes a lot of extra time.
You can actually make your own primer/bullet sealant with gunpowder and acetone. IIRC it is in the archives here on THR but really just mix to consistency.
Why have all the police duty rounds that I've ever seen been sealed?
Why are there companies specializing in sealing ammunition?
Just because you choose not to take the time to perform a particular step in order to increase the reliability of your ammunition doesn't mean that it's foolish or a waste of time.
As for expense, 18 to 22 grains of single base powder (I use old 4895 pulled from WWII AP rounds) in an ounce of pure acetone (not the oily stuff sold to remove nail polish) makes an excellent primer sealer and it's about as close to free as you can get.
If you like to use different colors to help ID your loads, just pull the guts out of an old, dried out magic marker and pour your acetone through that for color before you add the powder.
I'm not advocating that everyone should seal all, or even any of their ammo. I will say that immersion tests I've done on unsealed ammunition didn't give near the 100% sure fire results that others here have reported.
On the other hand, when primers are sealed with nitrocellulose and case mouths with Alox, I've had almost 100% percent fire rates with ammunition stored underwater at 5 psi gauge pressure (equal to @ 11 feet deep) for a week.
I only seal a small percentage of the ammunition I load, mainly large game and SD loads, but there's no doubt in my mind that doing so substantially increases the reliability of rounds that might be exposed to significant amounts of moisture.
Maybe because the military doesn't have the option to only shoot in fair weather?
