I am interested if there are some good stuff to apply on primer and around bullet to make it sealed ? (I only know there is Loctite Neck bonder, which is more crimp alternative than water sealant I think). What is used by large ammo companies ? Is it aviable to public ?

Thank you,

Jiri

Jiri,

I used to use pistol ammo in an adaptor I made for a spear gun. We used 357 and 44 magnum ammo.

To seal the primers against the water going in we used nail polish. It worked very well, and we never had any problems with it.

I think there is a commercial product available now that you can use for this purpose. I cannot recall the name, but it is blue and looks like nail polish!

Saeed: It's called George and Roy's Custom Primer Sealer. It's sold by Cabelas. I can't tell the difference between it and my wife's clear finger nail polish. I have used both without problems. Alan.

Thin lacquer 50/50 with lacquer thinner, color your choice. Prime cases and put them in a tray primer up. Dip a toothpick in the thinned lacquer and get a small droplet on the end. Touch it to the ring between the primer and case head and move it all the way around the primer. Capilary action will pull the lacquer in and when dry your primers will be lacquer sealed.
To seal a jacketed bullet seat the bullet about 3/4 of the way and then with the same lacquer run a ring around the bullet at the case neck. Seat the bullet to finished length right away. The lacquer is pulled in as the bullet is seated. If you do this develope load with the sealer in place because it may cauce a pressure increase as the bullet is released from the brass on firing.
You can also seal jacketed bullets with thinned tar but I've never tried this.
Remember to clean the lacquer out of your seating die.

Heh he he I once went Spearfishing with a South African guy, his name was Edward something, one (world)champion diver and a nice funny bloke. He gave me some powerheads(shark prevention and awareness) in 375H&H. make a lovely noise underwater....

You can put this stuff on your ammo, but unless you have conditions where the reloads will be immersed in water for extended periods, it is not necessary to do so. I still have some ammo I loaded in the mid-1960's in Alaska, where it was wet, foggy, etc., most of the time, and it still shoots the same as the day it was loaded....

Water proof your cartridges with red finger nail polish that way you will know the ones treated and the ones not treated. Clear works fine but red will tell you at a glance your cases have been treated.

I also use nail polish (Clear) but you can use any color that suits your fancy.
