I have a bunch of Glass silos from Dram works! They are the best! RCBS and Lyman 55's! I'm lazy I will not dump powders I use every week!
Unique, American Select , Red Dot & Bullseye are always full!

Like Ian said. Cure the powder correctly and it will not matter. I use every powder that Walter showed in that list. The only time I had problems was when I did not cook them long or hot enough. Once that was figured out it has not been an issue. I just pulled a couple bullets in my 9mm a few weeks ago to check them. These were loaded with titegroup. Nether had any powder stuck to the bullet or clumping. These were loaded 3 years ago.

BE and LS are in my stock, so just dropped several bullets into a jar with some 5744 just to see. Has anyone tested Power Pistol?



edit 4/10/23 : 5744 didn't affect my PC after 3 months in contact

I'd be interested in what Power Pistol does.
I don't have any to test, but I would by some if there was no reaction.
I bought thebBE-86 to use in the 10mm, but it seems to react with PC

Power Pistol does.
I tested my blend of Smokes Copper with a bit of HF red (added trying to get rid of it) with Power Pistol as I use it for my 38sp factory duplication practice loads. A month in a pill bottle submerged in powder did absolutely nothing. My ammo boxes hold 38sp ammo bullet down the partitions are not wide enough to take the rims. The ammo functions just fine with no noticeable difference in accuracy after a year and a half stored nose down. Your use may vary but I am convinced it is much ado about nothing.

I take it that most people who are powder coating their bullets are using the polyester powders with the TGIC cross-linkers. The only drawback that I can see to that is that TGIC is the mother of all carcinogens and without a really, REALLY good mask and extreme care in handling it's really tough to keep from inhaling it. For men who are still trying to father children, (like me), TGIC could be a particularly serious problem.

As a solution to that problem, some kinds of PC have been formulated to be TGIC-free and thus a lot less harmful. Problem is, like most things, that kind might not be as good. I also have found that there are acrylics and polyurethanes, as well as epoxies and hybrids. The epoxies are supposed to be hard and brittle, I would think that's not a good thing (HiTek anyone????), though the urethanes might have some promise and the TGIC-free polyesters might be fine, too.

Has anyone tried out powders that they know to be TGIC-free? I ordered some polyurethane a few days ago and will give it a go, will report how it does when I get around to using it.

Which powders ar TGIC cross-linkers.?

I am pulling a bunch of 9mm that is loaded with Power Pistol, Titegroup, SW Auto Pistol, 231, Bullseye. NONE of the powders are sticking to the bullets. These have all been loaded for almost 2.5 years. They are stored in ice-cream buckets and old coffee cans so they are in every position possible.

I'm new to the whole idea of "bad" powders..... I noticed on the Sherwin Williams website they list as one class of powder coat powders...

Superdurable TGIC Free Polyester​


Are they even considered as a viable source for powder? It seems that eliminating that would help in at least the "health danger" area.... not sure about all the rest of it, but..... baby steps?

TGIC Free​

means NO TGIC. Powders are either epoxy or polyester. TGIC is additive that helps cross linking.

TGIC is bad stuff to breathe! But, it’s great stuff for cast bullets.

In fact if memory serves it’s banned in the EU.

Yes. That is why I mentioned it. Previously in this thread, the dangers of TGIC were mentioned as a "bad" thing for polyesters. I only mentioned this to see if anyone had tried any of it, and is it a viable option for polyester powders that have TGIC in them.

In my vocabulary "bad" pc just does'nt coat as well as one would expect it to. I have a friend who has proper Powder coat set up. I sent him my bullets and "bad" powders. EVERY SINGLE ONE costed perfectly evenly with no holidays or hickies accept they had clean bases. (He could have stood on nose too)

I once tried some Sherwin Williams yellow and it covered poorly, but that seems to be a problem with other mfr's of light colors.
