There are probably many threads that would answer this but I tried the search feature and it didn't apear to work. So here are 2 questions! What should I use to weatherproof my hunting cartridges around the neck and primer? How would I searh for this answer using the searh at the bottom of a forum? I typed in "Weatherproofing Cartridges" clicked "search" and all the threads came back up.

I stock a primer sealer that should work around the neck also.
It is made by a brand called G&R or 'George's something' anyways, it costs $7.95 and should fit your needs.
I don't get much call for it in Southern California as our weather is less than damp.
Contact me through my website if you are interested.
I haven't had any complaints about it and those who have used it say it works well.

1, Why bother. The bullet has a .002 interfearance fit into the neck and the primer about .001 interfearance, water isn't going to be a problem unless your planning to swim to Isle Royal.
2, Try some of the wifes fingernail polish (get creative and use different colors for different loads).
3, buy some over priced gack that you don't realy need.

A friend of mine who is an avid diver and fisherman has an underwater "gun" that fires 45 acp shells using only a primer as propellant. His only waterproofing is a ring of fingernail polish around the primer.

I made some pretty wet hunts in Alaska, bullets in the bottom of the boat etc. Never had a problem, I would not worry about it.

I had a buddy that his wife washed and dried his 7mag bullets more than once, and they still went bag.

The military used to use a laquer around the primers. Now they use a Loctite product, I'm not sure which # (there are many loctite product #'s). The commercial primer sealants (like George & Roy's) are basically thinned nail polish with some blue dye. You can make your own by getting some translucent nail polish and thinning it a bit with nail polish thinner. Total cost about $4.00 for 7 gazillion reloads. Don't use straight nail polish. It is a bit too thick. Don't use opaque nail polish (Streetwalker Red, etc.). It doesn't penetrate as well as the translucent stuff.
All brass manufacturers and all primer manufacturers have perfect quality control so there is never any need for any primer sealant. < !--color--> That's pretty funny.
The military used to seal tracer rounds (and still may) with an asphalt tar. If you want to go whole hog you can smear a tiny amount of tree pruning tar on the sides of the bullet base.
In practice I seal all my duck hunting shotgun shells front and back, but don't generally bother with rifle ammunition. Picking nits is half the fun of reloading. If sealing ammunition gives you peace of mind, well it is a lot cheaper than Prozac.
Have fun,

PS Send me a PM and I'll send you a couple old articles from Handloader that you can read and make up your own mind on the subject.

First let me state that I have hunted in weather conditions that range from 55 below zero to 125 degrees above, and hunidity has ranged from 10% to 101%.

Secondly, I have never "weather-proofed" any of my cartridges, except for the loads I used in my Bang-Stiks while SCUBA diving.

Those cartridges were "water-proofed" with the cheapest nail polish I could find. Worked fine down to 150 feet.
