Powder Coating Cast Bullets!

I am trying something a little different with my cast bullets. Powder Coating!

I've been making and shooting cast bullets for some time. The only real problem I've had with them is that they are leading the barrels in my 9mm's. They also smoke much more than jacketed or plated bullets, which isn't very good for shooting at the indoor range.

So, yesturday I got a cheap powder coat setup at Harbor Freight ($58.00) and started to powder coat a few.

The powder coating works as the lube, so no more messy/smoky lubes are needed. The bullets actually shoot faster than either jacketed or lubed bullets with the same powder weights, so they are actually more slippery.

There is NO leading and there is very little smoke, just about how jacketed shoot. People have also reported better groups than lubed bullets, so there is a potential for better accuracy.

I've read that some people are pushing these bullets up to 2900 fps. with a plain base, no checks or anything.

Here's a large thread over at Cast Boolits all about it: Powder Coating Boolits

And here are a few I powder coated yesturday

Very interesting. The red/green/blue "boolits" (and others) in the link are cool. It all makes sense, please don't use pink.

I powder coated and loaded some Lee 358 105 SWC bullets for my 9mm. Going to try to get to the range this week to see how they work.

I really like how they look and how easy they are to load compared to the LLA coated bullets. A HUGE plus is that they feed through my Hornady bullet feeder VERY well, just like a jacketed bullet. So no more wiggling the feed tube to get the bullets to slide down like I had to do with the LLA coated lead bullets.

Just got back from the range. I shot a little over 100 powder coated bullets through the M&P. Accuracy was great and there was VERY LITTLE SMOKE. About as much smoke as when I shoot jacketed bullets.

I took the barrel out and there was only really powder residue in the barrel, no leading at all.

Here is the barrel after shooting. Sorry for the bad photo, it's hard to get the depth of field with this type of shot.




It took only one pass with a bore snake and the barrel is perfectly clean and shiny. Here is the bore after 1 pass of the bore snake.




I'll have to do more testing, but so far powder coating seems like it is going to work GREAT for lead bullets. No more smelly, messy lubes and no more smoke. Most importantly NO MORE LEADED BARRELS!!

Can't wait to load up some 155gr 300 BLK rounds to test out!

Most of the smoke from cast bullets is from the lube, and a significant percentage of the crap left behind in the pistol is from the lube also, so bypassing the traditional grease type lubes you have eliminated most of the disadvantages of cast bullets. I don't know how well this experiment will turn out in the long run, but it definitely has some good selling points up front.
