Primer Sealer?

    Hi all. Brand new to reloading here. Just got my Dillon RL550B and some supplies to get started. Been reading and reading some more trying to absorb all I can (so excited I can hardly stand it). Looking forward to contributing/learning more here on THR. Ok, on to my question...

    I came across a discussion online about primer sealer. Some stated they have used finger nail polish in different colors to mark different calibers to more easily sort their brass. Others say they have used it to identify particular loads of the same caliber. The consensus seems to be keep it lightly applied and it's fine. Any thoughts on this, good/bad/smart/silly?

    you'll find its a waste of time after a while. I did it but if you reload any volume you'll soon stop IMO.

    Unless you store your ammo under water, it is not necessary

    Right on. Could see how it would get old fast. And no underwater storage here.

    Haven't used primer sealer, or needed it in over 45 years of shooting, hunting, or reloading.

    I find it extremely helpful to identify different loads when Im testing a new round.

    You will find that your answer is mostly-silly.. The only use I have for marking the primers is to denote a different/closely watch type of load in a box of other loads.:)

    I've read Loctite works wonder, except you have to use the right type or decapping is a PAIN...
    but like the others said, unless you plan on burring your rounds for when the Commies come, don't really see any reason, and colored sharpies work fine for me.

    I use colored Sharpies for marking brass that is being reloaded for the last time due to primer pockets becoming too loose to load again.

    Only time I use sealer (nail polish) is when I load power heads for spear fishing.

    Two or three different colored Magic-Markers for me.

    As already stated, there is no need to seal primers, unless you are a Seal team member.

    Nail polish works fine. Helps if you thin it a little.

    You'll get different opinions, but I do the nail polish on my hunting rounds to make absolutely sure no moisture or oil can get into the powder on the primer side of the cartridge.

    I've soaked brass in soapy water for a week and found loaded rounds in with the brass!
    Marked them, single loaded during next range trip they always go bang.

    I last used clear nail polish for closing paper cuts, but switched when super-glue became available.

    For marking cases when developing loads, I, too, use sharpies.

    I don't see a need for sealing primers. I recently fired 200 rounds of 380 ACP loaded in 1983. Had one dud that had no powder. Maybe it leaked out because the case wasn't sealed? :banghead:
