hey guys, i have some black hills (LC brass) reloaded, and when i inserted the primers, they were easy... too easy. could this be a potential problem? i think i remember reading somewhere that you can effectively use super glue to seal primers, is this correct? any help would be great
 
clear nail polish works great.

+1. This has been the common man's approach for ages.

You are correct that long term-storage with loose-fitting primers can lead to failure (we had this problem in FL in the high humidity).
 
True. It'll also help you locate your fired rounds at the range.

"Hey, whose cases are these with the red nail polish on the primer?"

"Are they Midnight Kiss Red or Cherry Suprise Red?"

"Looks like Cherry Suprise to me."

"Yup. Those're mine."

:D:D:D
 
Any nail polish should work to seal the primers. What I would worry about is the primers seating easily enough for you to ask about it and think about gluing them in. Sounds like the primer pockets have stretched and may need to be recycled. Any time a primer goes in real easy, I chuck it in the bucket with a crushed neck.

I prefer Berry Red from the dollar store that has hardener in it. Don't wanna chip it off throwing it in the ammo can now do we. :)
 
In my September match, a loose primer came out and caused a FTF. I wasn't aware the primer was still inside the gun until it jammed the mechanism again on the next stage. So 2 malfunctions on 2 consecutive stages.

Loose primers cost me the match. By that I mean I finished last in my class... instead of my usual next-to-last!
 
Pitch the brass and if it was you who loaded them I'd take it down a notch. IMO a stretched primer pocket is the best way to know things are getting a little too hot.
 
these are once fired cases by black hills, unless they are maxing the charge, i doubt that that stretching is the problem. they have what looks to be a cut-out of where the military crimp was.
 
Maybe ther reamed them a little much. This is one of those things where I might set that batch of brass aside and get another to use while I figure out what to do with the first one. Maybe get someone else to look them over and get another hands-on opinion.
Maybe, just possibly, the primers are a hair undersized. Nah... just reaching a little. :banghead:
 
Whatever the cause, gluing them in with paint or super-glue is a VERY BAD idea!

If the primer pockets are that loose, they are getting dangerous to shoot.

Anyway, the pressure from firing is going to break any bonding agent instantly, as soon as the pressure hits it!

IMO: Pull the bullets & primers and save them.
It's time to Re-cycle the brass!

BEFORE YOU SCRAP THAT BRASS ,,,,

Try seating some Remington primers, they have done the trick for me where the primer pockets seem to heve been reamed rather than swaged out from the military crimps. Changing primers will of course require reworking your load data as may tend to change the pressure values on your current loads . 10 SPOT
 
+1 on the nail polish...

Take this with a grain of salt because I do NOT know if the heat and/or heat exposure time in a firing sequence would be long enough to do the same thing - but I once was dumb enough to try and solder something that I'd previously glued together with cyano-acrylic glue. Super Jet it was I think, but same thing as Krazy/Super glue. It liquefied, sizzled, and spit off this little puff of gas and nearly choked me to death while burning my eyes out.

Wouldn't want a puff of that coming up out of my chamber, for sure. No long term problems but I was miserable and wheezing for about an hour. Do NOT burn anything with super-glue on it outside a fume hood!

PS - if you're a fly tyer like me, head cement works well too. But if you can tell me the difference between it and nail polish, you're a better man than I.
 
The way I understood his question,
he is not asking about sealing primers to make them watherproof.

He wants to glue them in, to keep them from falling out! :what:

If that is the case, nothing will work safely.

I know of one particular manufacturer who has used a lacquer sealant for years that is essentially thinned and dyed nail polish. A very small drop (maybe a third the size of a water drop from a faucet) applied to the gap should wick around in a few seconds and be all that is needed to seal and lock the primer in place.

Your brass is completely and totally worn out. REPLACE IT before the heads start seperating, which is the next step in the usual progression of brass dailure

Commercial & military lacquer primer seal is used to waterproof the ammo.

It has nothing at all to do with "locking the primer in place".

Military ammo has a crimp applied to the case to keep the primers from backing out in Machine-guns.

Un-crimped & sealed commercial primers generally DO back out slightly, and then are re-seated when the case recoils against the breach face.

You can prove it to yourself by pulling the bullet on a lacquer sealed commercial revolver round.
Then fire the primer in a revolver.
The primer will back out and bind up the cylinder so it will not turn.

rcmodel, I wasn't thinking of machine gun applications. The lacquer sealant fractures easily. There are other sealants for specialized applications.

Loctite.

I've never tried this product, but I suspect this would be a permanent, one time application.

What part about "Nothing will work safely" does everyone have a problem understanding? :banghead:

There is no adhesive that will withstand the heat & pressure of a .223 going off.

If the primer pockets are so loose the primers fall out, the brass is scrap and it is not safe to continue trying to use it! :cuss:!
