Reloading powder coated bulletts for OEM Glock barrels.....

Thank you for your input but off topic.
I'm interested in bullet casters firing powder coated bullets in factory Glock 9mm barrels...

actually it's not off topic (speaking of off topic, this should be in the bullet making section) , If you can get traditional cast bullets to not lead in a glock barrel then powder coat isn't going to unless the coating wasn't cured properly.

I shoot mostly traditional cast and powder coated through my glock without issue, sizing is important. I size mine (powder coat and traditional) to 0.357.
 
Factory Glock 17, and have shot thousands of tool blue powder coated and a few batches of xmetal hi-tek bullets through it without leading issues. The coating stops the leading, just like a jacketed bullet.
As for accuracy, well, I don't shoot much past 25 metres but the bullets I used to shoot well if I did my part.
 
So, I fired my powder coated 9mm reloads through my G17 & my SP01. Both had clean bores to start. Inspection after firing 50 rounds through each pistol showed what appeared to be some kind of fouling, semi-dark and the same in both barrels.
Looked like the PC was smearing the lands & grooves. A quick swipe or two with a dry copper brush and a clean patch, and voila!
Clean! Oh Ya!!!!
Now considering powder coating my .44 mag cast 205 bullets...
 
I cast and coated some 9mm and shot them out of my gen3 g17. They keyholed badly at 20 yards. Shot the same bullets through a 9mm 1911 and the were all over the place but the holes were round at least. All the projectiles went through a Lee 356 sizer before loading. In the interest of transparency these were my first ever powder coats so I probably screwed something up.
 
The key to Powder Coating and the Hi Tek product is oven temperature. I have had poor success to date and finally have concluded my oven was not reaching the required 400F for the coatings to bond to the bullets. This spring I intend to try again with oven temp. above 400F.

To date though the amount of smoke generated is not significantly lower than using regular lubed bullets. Unless I find a performance enhancement along the way, for me, casting and lubing the bullets has worked up until now and I doubt I will make the change.

The process and product when applied right works. That there is no doubt. When you have leading like I encountered or bullets tumbling like others have, this is a result of problems with the application of the product on the bullets.

Take Care

I followed the directions that were included with my Tool Blue powder from Emerald coatings. 80-90% gloss can be obtained: 10 minutes @ 375F. So far my production has produced great results.

My PC bullets were fired from the 25 yard line into a dirt berm. While the recovered bullets sustained serious damage, the Powder coating appears to be ensuring that there is no leading. Just some soot marks on the lands & grooves....
 
Regardless of the powder (tried 8 so far) I bake them for 15-20minutes from a cold toaster oven at 400f. No issues of the powders scraping off and all pass the hammer test.
