I have seen sealer on military ammo. Is there anyone sealing there ammo and if so how do you apply the sealer to the primer and the bullet? I have seen the sealer at Midway.

Not necessary IMO. Primer sealant is used by the military since their ammo could be subjected to the most adverse conditions.

I think you're right. I have never seen anyone use it, just the military. I guess if I lived in a rain forest under some banana trees it would be a good idea. I think I'll spend my money on bullets or powder instead. :)

Primer sealer

Depends on where you live and how you store your ammo. Stored in surplus ammo cans or equivalent rubber sealed units, only need sealer on the primer in most extreme conditions such as military use. The one exception that I can think of off hand, is in very wet climates such as near swamps or such and very long term storage. I live in east Tennessee and have never used primer sealer and I have some ammo left that I loaded in the early to late 1960's. It still shoots fine, with no misfires. I have always bought and stored my ammo in surplus 30 and 50 cal ammo cans. My experience anyway, James
 
But, just in case you want to seal some and bury it in the back yard. just get some nail polish (your choice of colors).:D

Thin it a bit with acetone, brush it over the primer and then wipe it off. It will stay in the groove around the primer.
 
I acidentally ran a full speedloder with 6 .38 Spl reloads (Federal cases, HP38, Federal primers, and Berry 158gr) through a full wash cycle.
Curious about what damage I had done, I fired them over my chrono that same day.
The cartridges all gave normal speed.

I don't use sealer on my reloads.

I doubt it is necessary for most purposes bit I used to use a streetwalker red nail polish on the primer as way to mark the ammunition I loaded for hunting.
 
I'm glad to know I'm not the only one that's accidentally washed bullets...
 
Sealing primers is a waste of time for normal reloads. Military ammo is sealed because it's meant to be stored for decades under adverse conditions and still function.
 
If you are going to seal the primer, then you better seal the bullet in the case too. To kill a primer takes a a lot of bad luck, so don't worry about it.

Years ago I tried killing primers and loaded 100% filled primers with WD40 and CLP, most primers after 1 week, still fired. Not as strong, but they still fired. I never thought of the water in the primer but it might give me something to do as the snow melts.
 
I have also run ammo through the wash and it has fired without problems.

On a somewhat more disgusting note, I have had armpit sweat drip down onto my concealed carry moonclip reloads for the 625 that I carry on my belt. My sweat stains the nickel plated cases and primers but they still fire.

I have thrown various sealed and unsealed steel case 7.62x39 into salt water for five days just to see what would happen. The only ones that fired (and with complete reliability) were those that were sealed.

I have never used a sealer on any ammo I've put together and probably never will. (unless the big war comes ;))
 
I was curious about how tight a primer was in it's pocket, so I loaded three 9mm normally and put them into a Tupperware container full of plain water.

Five weeks later they fired normally.

However, I usually carry handloads and those handloads are sealed using George & Roy's primer sealer. Just to eliminate one more variable.

I use my reloaded ammo strictly for target shooting and informal plinking, so i have never felt the need to seal the primers. That said, I have NEVER had a FTF with any of my loadings.

For self defense work, I use Buffalo Bore Ammo (factory) which is sealed.
