A partnership for powdercoating.

Yes, we are talking about "projectiles" and not "loaded ammunition".

As to the focus of the thread, both blarby and I have been curious about powder coating of lead bullets and have read various "alternate powder coating" threads at castboolits forum.

What I have read is that different people were getting different results with different products (brand of PC powder, brand/type of plastic container, brand/color of plastic BBs or multi-facet plastic beads, etc.) and different coating methods (swirl/shake vs plastic/ziplock bag methods etc.) along with baking temp/time (20 minutes at 400F vs 10 minutes at 350-375F).

As many of you already read in different threads, some will post they have easy and great success with XYZ powder coating methods while another will post that same methods did not produce good results at all. Like the Mythbusters TV show, I was interested in testing and verifying which methods worked and which did not so as to determine a certain "standardized methods" that would produce the best results.

Since I do not cast, blarby's offer to provide that service was much appreciated "partnership" with results that will probably benefit many other THR members and guests.

Going into this project, we already have certain amount of premise that will undoubtedly be verified but it's sometimes good to confirm what you already know. I think both of our particular interest in this project is the compatibility of powder coated bullets in Glock barrels, specifically in 40S&W regards to accuracy and leading. It's my guess at this point that they are compatible and if that turns out to be the case, along with the benefit that completely encapsulates the lead bullet, it will be a win-win situation as to cheaper, clean loads that are accurate without the worry over leading.

My particular interest is .300 BLK loads with 230 gr bullet. If successful loads can be developed that are accurate and clean, then cost savings over jacketed bullets and worry over lube/lead/fouling of gas tube will be a huge plus for me.
 
Indeed.

Once we have a "base" process that works using the bb/#5 method, we'll branch into other areas of application.

I have all of the projectiles for the first run cast- just waiting on a few pieces of kit.

Pictures of the bullets coming tonight.
 
Thank you both for taking the time to go through this and post results. Im really looking forward to what your testing reveals as I am about to start gathering the stuff to do this for my 300blk.

The main reason I want to get into this (for those that care) is to shoot subs through a suppressor without leading it for a fraction of what it costs to do the same with jacketed bullets. Heavy 308 jacketed bullets are too expensive for me to plink with, but to be able take some lead boolits, powder coat, size, load, and shoot for almost a quarter of the price and Im all in.
 
As posted in other powder coating threads, some are getting good results in terms of coverage and thickness of coating (which are the primary objectives) while some others are getting poor results (thinner coating / less coverage).

Hopefully, we'll be able to demonstrate step-by-step processes that produce good repeatable results with "known" variables like:

- Brand/color of powder
- Static electricity generation (#5 plastic container, brand/color of BBs, etc.)
- Method of coating (swirl/shake, plastic/ziplock bag, nitrile glove, etc.) for 99% coverage
- Method of holding coated rifle bullets (drilled cookie sheet, wire rack, etc.)
- Tray liner for pistol bullets (non-stick aluminum foil, parchment paper, silicone, etc.)

- Ambient temperature
- Ambient humidity
- Temperature of the bullets (cold vs warm)
- Bake temperature and time (350/375/400F at 10/20/30 minutes)

- Other variables like type of alloy (wheel weights vs foundry alloy), water quenching for hardness, sizing of bullets, mould shape, etc.
 
I use the Lee C312-155 for my 300Blk.
Amazon has them for 20ish. 80grs less lead per round. Supersonic only though.

Oh well. I dont even have a suppressor!
 
So have you shot them powder coated? If you have, are you getting any leading?

My thinking with the heavier 230 gr bullet is to shoot at lower velocities around 1050 fps that's already been proven to be effective with powder coating and not for suppressor use. blarby has other 30 caliber bullets so I was planning to test supersonic loads after success with subsonic loads.
 
I would like to know if the black a.s. bb's have any carbon fiber in them which would cause them to make more static? If some one had an old microwave to cook them in they may spark a bit if they have carbon,just a thought.

I was starting to get lead buildup on my standard lube loads in my gas system... so I switched to PC.

Have a bunch loaded but havent made it to the range yet.

OK pc came out great .45 cal and .30 cal all look good strait coww h2o dropped then pc'd,.30cal h2o dropped after pc .45 air cooled I'll load and let you all know how they work ie grouping.Sorry I don't know how to post pix.

Great, really interested in the .30 cal results.

Speaking of images- my "image maker" is having fits and starts.

photos to come once it works itself out...

Did get the HF red today. Still waiting on the last shipment of sizers, and most importantly the BB's.
 
Hey Blarby, If I don't forget again to check on it when I get back to town, how am I going to PIF you some lead for the project if I don't have an address?

Also can you ship lead in a flat rate box and if so how much weight an be put in it?

If the information I got is correct I will have a bunch of pure lead coming your way soon.
 
Was late last night when I got home, but I tried 40, 401 tumble lube truncated cones.

Wanted to test temperature and "flow"- see what kind of coating imperfections might "fix" themselves in the curing process.

You will get some very minor flow, but not anything exceptional. Nice thing is, doesn't really matter what you do to the tips, as they never touch the bore.

Not a bad first try.

Thats a pretty nifty coating.

400 degrees for 12 minutes.

I have been PCing for several months. I dry tumble, "wet" tumble, and spray. I have had very good results in 9mm, 45 ACP, 38 Spec/.357 Mag, .314 for my MN, and .309 for my 30-30. I have some .308" 185 grain PCed bullets I'm going to try in my M1 soon. PCed bullets aren't any more labor intensive than other, traditional lubes. They are much cleaner to handle and cleaner to shoot. PCed bullets don't smoke when fired. PC won't dry out and crack/fall out of the lube grooves. Plus no leading and very little fouling. They aren't a "poor man's" nor a "rich man's" anything, they are just a different coating/method for the home/hobby ammo manufacturer. Traditional lubes work, but PCing may just work better, just like that new fangled smokeless powder may be better than black powder...

blarby, looking good for the first batch!

mdi, yes - we spent a lot of time reading the various threads at the castboolits forum and I think many owe their success with powder coating to the hard work and ingenuity expressed in the threads.

Caster/reloaders helping other casters/reloaders! :D
 
2nd coating.

Cosmetically much better.

Not sure what that adds to functionality- or sizing.

We'll find out today.

430's are in the oven.

Gloves work far better for removal than any pronged instrument. Removes much less PC.

430, 240gr

These were coated the same as the 401s, with one exception- a 5' drag across my carpet for more residual static charge.

I see a marked improvement, these are a single coat. They look better than a double coat.

Sized 401, 1705gr TL

There was no shearing of the coating during sizing, and they sized very easily on the lee push through.


Already my desire to use the LLA tumble method is fading.
