What about using nail polish to seal the primers?

    I got a few boxes of dirty ammo from Winchester, crud around the primers. I'm scrubbing them and cleaning the crud out but I'm worried about taking off the sealant.

    I read from someone here on this forum that they just use nail polish for sealer.

    Is nail polish OK?

    Had this same problem. Call them and they will have you send them back for a refund. They were very interested in having their quality control department look at it.

    I agree, there's no need to seal them...

    there is a pretty good article in the latest issue of American Handgunner magazine about waterproofing. while I don't think it is really needed I was surprised by the article

    That's correct....there is NO NEED to seal them.

    Over the decades of my handloading, a few rounds have accidentally been run through complete cycles in the washing machine. The number likely adds up to perhaps fifteen or twenty rounds. EVERY SINGLE ONE of those rounds fired normally.

    I use plastic-model paint of many different colors on the primers of a good bit of my ammunition, but it's done for identification purposes, not as sealant.

    So taking a toothpick and putting a little nail polish around the rim of the primer won't hurt anything right?

    I'm thinking it will give me peace of mind.

    I am going to call Winchester on Monday, I'll send them the pictures.

    I guess what I'm afraid of is

    1) I'll have to pay shipping - that's $16.00, I could get 50 rounds of Speer Lawman for that

    2) Instead of sending me nice new RA9T in return, Winchester will just refund my money - I've been looking ALL over for these things and none of my local gun stores sell them and I've been looking onlne for 6 months and they have been out of stock for the longest time. If I just get a refund for the purchase price - I still have to find on another online dealer (I don't think I'm going to order from the same site I ordered from last time)

    And then I have to pay shipping AGAIN for the new batch of ammo...

    Not sure nail polish was used to seal the primer, seems the reloader? pushing the nail polish thought it was good stuff to hold primers in primer pockets that were loose.

    Then there is the cleaning part, I have no clue if the part to be cleaned is coming from the inside out or if what ever it is that is bothering you is just on the outside. If I was concerned I would pull a few cases down and examine the components, if the primer pocket is clean, the primer is clean and if the powder is not caked up I would apply the ‘Leaver policy’, I would leaver the way I founder. And, If I was concerned about leaking primers as in the exchange between the atmosphere in the inside of the case with the atmospheres outside the case, I would do an atmospheric exchange test, because, I am the only reloaders that can preform a vacuum test without a 100% (perfect) vacuum, I could do a pressure/release test, most dangerous unless a pressure container is not available, anyhow a vacuum test is the safest of the two methods.

    I do not know if the ammo you purchases is new/old stock or if someone reloaded the ammo and sold it to you, a lot of that stuff goes on when there is a demand and no supply. Next time purchase two boxes then take one to the range and determine if they fire. If there is a reason for the mess on the outside coming from the inside painting the case head will not stop the problem.

    It was me who stated that I use nail polish, painted on, thin layer, enough to fill the indentation around the perimeter of the primer. I get it on the entire bottom of casing and wipe the excess off the entire bottom using the nail polish brush. This fills the primer perimeter void that is there from the rounded primer against the 90 degree case primer pocket.

    I was NOT using the nail polish to seal LOOSE primers, but was instead using it to seal primers that were a bit easier to set than all the other primers. If a primer is so loose that I question whether it will fall out, that case gets trashed right then and there!

    For cases where I have decided the primer is easier to seat, I consider those cases to be good for one last shot, in which I will then mark the bottom of the case to know not to bother picking it up, or pick it up to throw it out when I am done shooting.

    The nail polish is only used as an attempt to help prevent any gases from possibly going by the primer and pocket.

    In over 30 years of reloading, I have yet to have any signs of gases escaping around the perimeter of the primers, so I can only surmise that my method of tossing extremely loose primer pockets and only saving and then marking those which seated but were a "bit" easier to seat than normal is a good method that works FOR ME.

    You can't remove primer seal, even if you tried.

    The part that matters is down inside the primer pocket sealing the cup, not on the outside.

    Forgadaboutit!!

    Even George and Roy's primer sealant is nothing more than clear nail polish

    Unless you regularly go swimming with your ammo in your pockets, sealant isn't necessary

    Winchester will cover the return shipping. However, they will likely only send you a refund in Winchester coupons. If this will not work for you let them know.

    Unless you soaked them in lacquer thinner or acetone, there's no way your removed the sealant.
    I don't worry about sealant on practice rounds, but I like it on serious stuff.
    I had some .40 cal aluminum case Blazers go bad after spending a week in a wet plastic bag. About half the primers failed to go off.

    ^ Agreed. There's a bit of visible sealant around the curved top of the primer. But that's not what's sealing the primer. It's the little bit that gets between the primer wall and the pocket that's doing the work. If your brush can fit in that space, then that's some seriously defective ammo.

    There is NO amount of sealant applied to the outside of a cartridge that will prevent the escape of combustion gases - the pressures generated inside the case are substantial to say the least and some Revlon #5 in cherry red ain't gonna stop them - lol

    As several have said here - there's just no reason to bother with sealant.

    Well, if for nothing else, it tells me which cases I am not going to reload again. Whether it has ever prevented a bit of gas from being expelled, in over 30 years, I never had it happen with this system, so I could not say for sure that the stuff absolutely, without a doubt, did absolutely NOTHING.:uhoh:

    I guess I could write it up as one of those 'feel-good' things.

    I, use nail polish for marking my diffrent loads. One of the advantiges is it will provide some level of protection, but this is not the main resone to do it.

    FWIW, there are different grades of factory applied sealants. Nail polish is pretty close to the 'standard' grade. I'll let the smart ones figure out why nail polish might not be up to the task in some applications.

    One day I went to a WV park and spent the day swimming in the creek with my P32 in my pocket. It was in a plastic bag but I noticed pretty quickly the bag wasn't as waterproof as I thought. The ammo was soaked in the creek all day long. I went the range later and all the rounds popped off just fine. I think most ammo seals up pretty well. If I was a Navy Seal I might be more cautious but I'm not so I don't worry about it.

    I haven't loaded anywhere near as long as you have, but I have accidentally soaked a number of reloads that all fired normally. I even dropped several into my 2' deep pond and had trouble getting them out. They fired.

    Just another thought: Do you use soft or hard primers? Soft primers probably would conform to the primer hole more reliably. The Russian imports and maybe CCI are hard enough to not "size" to the primer hole "every time they are seated". I use soft FEDs but never though much about primer hardness vs seal until now. Maybe a non-issue--

    I use your method for marking a rd that "the primer went in a little too easily". I shoot it and don't reload it. Works for me.

    I'd concentrate more on getting treatment for the OCD and less about sealing primers that don't need to be sealed and paying shipping charges, etc.!!!:cool::evil:
