ROBOCO LABORATORIES - Bullet and Primer Sealer

The product is great, want ammunition you can count on,Markron it!!

I bought 2 bottles of this bullet/primer sealant a few weeks ago to try out, and I have to tell you all, this stuff is GREAT!! I do wish it was just a tad bit more viscous, so it would just flow around the primer pocket of loaded ammunition. Its not thick, you just need to put a tiny drop on two sides of the primer pocket, and use your finger, thumb, or toothpick and press it around with a sort of circular motion with your thumb, while wiping excess at the same time, and it leaves a perfect looking sealed primer. The toothpick you do the same with two tiny drops and use the toothpick and push the material around following the primer pocket, then wipe away excess. But the real cool thing is you can use this stuff before you seat the primer or the bullet, by placing a tiny bit around the primer pocket opening, then seating primer, and place a tiny bit around the inside of case mouth, before seating the bullet. And according to Markron you dont have to worry about extra pressure in your ammo, they claim its completely safe. Another pro for this product is its use for loose primer pockets, dab some of this around the primer pocket, seat your primer, and there you go, a little extra grab for the primer. And if you want more grab, hit the primer again after youve seated the primer. All in all this stuff is a excellent investment for your ammo, for a reasonable price, especially from BROWNELLS.COM. I have TWO MORE BOTTLES in route. Oh and as for the viscosity, I plan to call Markron and find out exactly the right thinner to use for this stuff, to reduce it just a teeny tiny bit more. Its either acetone, or lacquer thinner, they state that clean up is done with lacquer thinner, so thats probably what theyll tell me. But theres nothing wrong with the way it is now, I just want a tiny bit better flow, so it flows by itself in the primer pocket without help. Ill thin one and leave the others full strength. Great stuff!!

I wanted to seal some ammo for long term storage in my humid climate and also hunt in swamps where it's not unusual for me and my ammo to get thoroughly soaked. I use it on my rifle. pistol and shotgun shells and have never had a misfire. I have even soaked some of the sealed and unsealed ammo (reloads) for 7 days to see what would happen. I had a few misfires from the unsealed ammo and none from the sealed. I don't plan on leaving my ammo underwater for any extended period before using but I can now feel confident that when I get soaked chasing pigs through the swamp that my ammo will fire.

I hunt in the wet in Washington. I've always had reload misfires in the past. Since using the sealer I've not experienced one misfire on my hunts. It's a great product.
