Problem with High-Tech Coated Bullets

Have you ever tried PC? Let me know if you DO as a comparison.

Maybe these did not CURE properly. Bake a few in the over at 400 deg for 15 minutes or so. So how they are then...

I've shot a lot of these in .40 s&w-mid range to red hot loads with tight group and w231. No issues....

Too much crimp? Lee factory crimp? Mic a couple for diameter?

I'm snatching at straws here but I can't think of anything else that would strip that coating and cause leading.

No, I've never used PC bullets, only Jacketed, Plated, and Lubed Lead.

You might be on to something, I seem to recall one of the bullets seemed to feel a bit gummy but I didn't think anything of it since all lubed lead bullets feel a bit gummy. I only noticed because I had to hand place them, as they wouldn't work though my bullet feeder. I'll have to dig some out of the scrap bucket, and put them in the oven, but I've got to tell you I'm none to anxious, to run them though the gun.

Alright, I'll have to dig some out and measure. Yes, I do use a Lee factory crimp die. Crimps always measure at .471 to .472, if they go much over that they get a bit tight in the chamber.

Someone correct me if I am wrong, but HI TEK pills should NOT NEED LUBE. so they should not be gummy. They should be dry and sound ALMOST like marbles. They should feel slick to the touch. At least my PC ones do.


Who was the manufacturer you bought them from? It could very well be that their oven is going bad on them and not curing properly. Everyone makes mistakes. No biggie. Who they be?

[TexasJackKin]

OK, I dug some out of the scrap bucket, they measured .454 to about .4565, that was measuring over the coating.

You are correct sir!

Uh oh...ACP diameter is .452. Could these be colt pills, or just a defective batch?

Time to call the vendor/manufacturer.

The box says .452, I'll admit with these bullets I don't know if the .452 measurement is before coating, or if that should be the coated dimension. As I said, over the coating they were .454+

^^^Well, my hi-tek .40 pills came from MoBuCo. Box sez .401 dia. I just measured 6 and they were all .401 +.0005/-0.

Also IIRC the powder coaters here would run their coated/cured bullets through a sizing die.

I think you got either mis-boxed coated colt pills (.454 dia) or these are defectively over sized.

Yup, I'm starting to think you might be right, I split an order with a friend of mine, I'll have warn him, Thanks.

How hard was this leading that you see to clean?

Several Hours, never had an issue like this before.

Well thank gawd. I was startin' to sweat bullets... (pun intended)

Resize a few and see how they run then.

And yes, we want ACCURATE PC pills, so I will run all of mine through a Lee sizer after they have cooled down a bit. Although I DO have a large bucket filled with unsized pills. I really should size them, maybe when I need more of them for something.
