Industrial Reloading Sealing System, Waterproof Ammo Primer Bullet Sealant (Red)

This product is a great primer sealer, enough to seal over 10000 rounds or more in the bottle.Used a small plastic squeeze bottle with 2" metal tube to apply which Amazon also sells.It ships from Ukraine so it does take a month to get here.

This sealant works well. Plain and simple. I use a toothpick to apply it instead if a paint brush. Brush applys too much.

Works great as advertised and holds up nicely to water "fully submerged" for extended durations!

I have used 3 other brands of ammunition sealants; trying each only one time.RangeR is the easiest to handle, especially if you aren't using an automated system. This has enough volume that you can apply it with a toothpick, a syringe or decent quality needle tipped plastic bottles here on Amazon. I use 70% isopropyl alcohol for cleanup; some really cheap bottles are one use only. My routine is to load 1,000 rounds and to put the assembled cartridges in plastic ammo boxes, primer up. Next step is to put a thin but sufficient bead around all the primers, then set them aside overnight. RangeR Sealant dries pretty quickly, but this is my routine. The next morning, I get a set of plastic pistol cartridge boxes and flip the dried ammo into them. Using the pistol boxes allows full exposure to apply Ranger to the projectile/case joint. Once it is dry it goes into ammo cans with ULine desiccants and Brownell's gun wrap paper. This item is also an excellent way to keep freshly polished brass bright for over 5 years.This is also great for sealing rimfire cartridges. This product isn't really brittle, so your hard handled .22LR will fire the same in 5 or 10 years as the first day you bought them. Using a chronograph will shock you how quickly rimfires lose velocity from moisture vapors getting into the powder.I If you are loading a fairly large amount of ammunition for long term storage (concerned about a fall of the thin veneer of civilization?) this product is what you need. This is the sealant used on Russian ammunition for decades. I had 1917 Russian anti-tank cartridges originally sealed with this and all 1800 rounds fired as though they were loaded yesterday.Use the different colors to segregate your ammunition. For 5.56 you can use one color for M193, a different color for the various heavier bullets you might use, another color for monolithic copper and another color for your specialty rounds such as DRT highly compressed powdered tungsten projectiles. When you are instructing a new shooter or taking an old friend to the range a quick look allows you to make sure your higher cost rounds aren't being used to punch holes in paper.I don't know if the 25,000 cartridge number is one seal per cartridge or both primers and projectiles. I do know that I get over 10,000 cartridges sealed at both primer and bullet without needing to be conscious of spills or cleanup loss. Other brands claim 1,000 seals from a .5oz bottle. This RangeR Sealant is the most economical I have found.If you are serious about long term ammunition storage, always ready as the day you loaded it, you really should buy this RangeR product.It has been arriving in Florida this year in 15 to 20 days.I soaked 250 rounds for 3 months in KROIL cutting oil. All fired and chronographed with no variations from the original date of assembly.Send your money to Ukraine to help people that need your currency. You will get the best product available for a good price.

This stuff works great.
