Gold Dot sealant

[roar]

I am wondering how good the sealant is that is around the primer and case mouth on the .38 spl +p Gold Dot Short Barrel round. You can easily see the blue sealant around the primer, but the sealant around the bullet is invisible.

Would it prevent the cartridge from being ruined from possible contact with oils or gun cleaning solution such as M-Pro 7? I'm not talking about being coated in the stuff, but if the cartridge came into contact with a tiny bit of water, oils, or gun cleaner. Any experience?

I don't know about lubricants, but I've shot sealed ammo that's been through the washing machine and dryer. I sometimes forget to take the Speed Strip out of my back pocket. It's always worked fine, although if you try it, you should inspect the bore after each shot to make sure you didn't have a squib that left a bullet in the bore.

I just remembered seeing this a while back. It's good fun, even if it doesn't exactly answer your question.

I've submerged rounds in different oils for days, they all went bang......

The bullet is press fit into the case. Should be watertight even without sealant.

Thanks for the link, and information everyone!

jlanecole,
here's another test for you to perform if you are so inclined. When I reload, there is usually at least one (out of a thousand or so) cartridge that I notice is so badly split AFTER I have pressed in a new primer, that I choose not to reload that one. I use a few drops of WD-40 or other penetrating oil to "kill" the primer and dispose of it. I have been doing this for years, but recently saw an article (can't remember where) that states that when the WD-40 or oil evaporates, the primer will become live once more! If his is true, then killing a primer is a lot harder than I thought all these years. I suppose the only safe way to dispose of it is to pop it in a gun. Let me know what your findings are if you choose to test his out.

Regards,

Keep in ind that Gold Dot was developed with police use in mind, in cooperation with NYPD. It is now used by many other departments as well.

You can be pretty sure that it is well sealed. This is premium ammo, marketed toward police use.

I used to seal my carry ammo with finger nail polish (I know, paranoid right)

Then I decided to do the submerged oil test of Factory loaded ammo.

I used Kroil, Breakfree, WD40, Remoil and a few more I can't remember.... I believe the test period was 7 days submerged.

I dropped in 10 rounds of each caliber in each container of oil and let them sit.

Took them all out to the range, gave them a quick wipe off and loaded them up. Zero ftf's or anything out of the ordinary.

I'd say you're covered....

I believe the idea behing "sealing" is more than just to keep oil and water from seeping in. In the case of extreme climate changes, where the weather gets very hot then cools off, it creates a vacuum inside the cartride which could actually draw unwanted moisture or oil into the case. Sealing prevents this by keeping the air inside the case to start with.

This is just a theory by the way, I haven't tested it to confirm or disprove it.

i have fired a few that accidently went through my brass tumbler...they went bang for sure!

I ran an 8 round Tuff strip through the washing machine (forgot to check my jeans pocket before washing, left my reload in the pocket accidentally), took those rounds to the range a couple of weeks later and they all went bang without any issues.
