Powder Coating Cast Boolits!

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: http://castboolits.gunloads.com/show...oating-Boolits

And here are a few I powder coated yesturday

Wonder!

If there is any extra wear on the rifleling?

What sort of residual are you going to leave in the barrel from the powder coat? You might be opening a can of worms for yourself. See if a buddy wants to shoot a bunch through his gun first.

No, the coating is slicker than either lubed lead or copper jackets, so there is actually LESS wear.

You can also use softer lead with the powder coat as the bullet will not lead the barrel, so there is less wear than using hard cast bullets.

I loaded up a few hundred 9mm powder coated bullets. I used the Lee 358 105 SWC mold and 4 gr of W231.



I shot a little over 100 powder coated bullets through the M&P at the range today. 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!

No residue at all! Just the normal powder left over. As you can see in the photos in my last post, the barrel was spotless after only one pass of a bore snake.

Can't beat that for an easy clean. It is even easier than cleaning after shooting copper jacketed bullets. No copper fouling to deal with.

Did you get the barrel hot during your test shoot? What about the neck between the chamber and barrel? Was there any buildup of material there?

Looks cool so far. Interested in the response to JamesG's questions.

A bit of advice: Be careful about using one of those to shoot someone. They might well get an infection from that powder coating stuff and that might well cause them to suffer harm, or even death.

I was shooting at an indoor range, so no, I don't have any recovered rounds.

Here is a photo from the Cast Boolits website though with some recovered rounds. You can see that the coating in the rifling is still intact.



And here are a couple of powder coated bullets smushed in a press. As you can see, the coating is pretty flexible and REALLY adheres to the lead.

Nah, I think Nyclad was something else, coated Teflon I believe.
