Default Primer Sealer

Trying to find the point of primer sealer, not new to reloading but having trouble seeing the point of why anyone would use it, maybe for loose primer pockets? I shoot a lot of handgun and can't help seeing brass laying around that has been sealed and wonder why.

Primer sealant is used to seal the primer against water, oil, contaminants, etc. It is most commonly used only on military ammunition which may be stored for long periods of time and used under adverse conditions.

Thumbs up

The brass you see lying around is probably S&B (Seller Bellot)

Or it could be any other quality brand of commercial ammo. Sealants, both primer and bullet are one of the little differences between top of the line ammunition and promotional fodder, better known as "white box", "yellow box", "red box" or etc. Just because you don't see it doesn't mean it's not there.

The decision for me to use it depends on what I'm going to do with the ammo being loaded. If it's for the range or a bucket full to shoot varmints with on a nice warm day, no. If it's for long term storage, self defense or a once in a lifetime hunt with the possiblity of bad weather, yes.

Unless you're aiming to play Navy SEAL or hide you ammo in the toilet tank, it's a waste of time and money.

I've been on hunting trips where I've been in the rain for days at a time, and have thought of using some primer sealer. Luckily, whenever I've pulled the trigger, it has gone bang!

I will remember that next time I have to spend 99 cents at the dollar store and take less than a minute with two full loading blocks. Maybe if I bought a third it would take that whole minute. The clear has done a few thousand so far and the red is still mostly full. And my ammo has no fear of over zealous oiling of guns in Florida or the rain, humidity, or sweat. So thank you for your comment.

Well since he visually sees it, it is therefore visible and not clear. If it's at a range I doubt that folks are sealing their own just as as range blasting ammo,or using the high quality invisible sealant such as yourself but there again what do I know?

I see quite a few empties with red sealer. Look like they've been reloaded multiple times. One of those "to each their own" things I guess.

What I'm saying is that most quality factory ammo has it, and it is often a clear sealant that covers the entire cartridge or at least a spot on the primer and a ring around the bullet. I've noticed red sealant on several brands of factory ammo and not just one and have found it laying around a range too, I have no doubt that it is factory loads.

The high quality of visible sealant that I use is nail polish and in addition to that I use whatever color the wife buys and decides she doesn't want.

And since you asked, I don't know what you know, but it obviously isn't "everything".

I only answered by ID'ing one brand that is common and very often found at ranges. He can't see it if it's clear which despite your comment I do know there are sealants on other brands

We leave the knowing of everything to you.

When I go on Safari I have my custom Weatherby Dangerous game ammo coated in a propriety Mauve coating.

Another use is to identify a loading. Particularly if you have a batch of reloads you load up in pressure for use in one particular gun. It can be a warning if you've got a half dozen rifles or handguns in a particular caliber and don't want to use those rounds in other guns.

Somewhere I've got a bottle of green sealer. It came from some maker, like Ben and Jerry's (something like that and I'm too lazy to go look for it.)

Just be sure you make good notes as to what color primer seal goes to a certain gun.

To get a good seal I agree with the idea of thinning. Some acetone does that task. Then just a tiny drop on a cut back brush will apply it. Once it hits, surface tension runs it around the primer. Just don't use too much. It can crack off and all litter/debris to the action of a semi-auto.

There are several commercial brass processors that seal the primers as part of the operation. I suspect the equipment once belonged to the gov't ammo producers, and was sold surplus during the Clinton years.

If the primed brass costs the same sealed or unsealed, I'll take the sealed stuff.

I seal the primers on my hunting rifle rounds more as a just in case thing than anything else. I use clear nail polish that I think cost something like 98 cents many moons and many rounds of ammo ago. Still using the same bottle...

I use cheap clear nail polish for sealing primers and as a "better than loctite" thread locker. It keeps my nails from chipping in the winter, too.

Kind of a newbee reloader here, but is the sealed primer ammo reloadable due to not being able to push the primer back out because of the sealer?

The seal breaks easily when deprimed.

I would think sealed primers, and bullets for that matter is a good thing considering the number of guys over the years I have seen spray their guns, ammo included, at the range, with penetrating oil, before they re-holster at the end of the day..

Modern lead styphenate primers are largely unaffected by weather and elements. But if you chose to go with lead-free primers like Fiocchi then you must use sealant.

Primer sealants aren't just for the primers benefit, it's because that is a way for moisture and contaminates to get to your powder.

Quality factory bullets are usually either coated with a clear sealant, or they may be seated using asphaltum that not only seals the bullet against moisture and contaminates but also increases the amount of "pull" required to move the bullet. This is to make sure the bullet doesn't move in or out of the case during the most extreme handling or harshest situations, and helps powders ignite properly in a wide variety of climates and temperatures.

Default I used to use nail polish on my 38/357 rounds

But that was only to seal against salt water on my bank stick I used when I use to dive Anacapa Island. Unless you intend to submerse your rounds in water ,it's a waste of time I think.
