I know some of you guys shoot powder coated bullets,and you coat them yourself. I just started doing some powder coat,using the shake and bake method. Last weekend I bought some powder coated bullets at the local gun show. The guy uses a powder coat gun,so that means the base of the bullet isn't coated. What is your preference on this,should the base be coated or not? Have you shot both and saw any difference in the two ways to coat? Dryflash3 ,I hope to hear your opinion on this, I know that you shoot powder coated bullets!

I coat my own so the bases are coated. It wouldn't bother me if they weren't.

If the lead base of the bullet isn't coated, the powder used to reload could result in smoke and fouling.  Hot powders will burn (not sure if that's the right word, or atomize) the lead resulting in additional smoke and lead related fouling in your barrel. Tightgroup powder and coated bullets are well known for this; do a search.

I coat my own, so my bases are coated.

According to the folks on Cast Bullets forum, it doesn't make a difference.

Thanks for the replies guys. My thoughts were that the powder burning against the bullet base would add lead to the barrel and put lead residue into the air also but I thought I should ask others experiences\opinions!
Anyone else have an opinion or experience to add?

I just started, but for the most part they'll be shot through suppressors, so I make sure the bases are coated.

As dryflash3 posted, it doesn't make any difference.

This un-coated base thing comes up all the time and you'll see all sorts of things about melting bases and a lot of other BS. Fact is the only time the un-coated base is effected is when the bullet is exiting the barrel. If you are not using a muzzle brake or "can" this is a non-issue.

Just remember while powder coating often expands your usable load range it's not a substitute for a gas check. At least it hasn't been proven to be yet.

Thanks for the reply Motor,I wondered about shooting them thru a can also. I know the PC wouldn't replace a gascheck,but I don't plan on pushing them fast enough to need one.But maybe later,you never know.This PC deal could be addictive,and spread to my other calibers.

You will be surprised on how much faster you can push a PC bullet without a gas check, and not have any problems.

With waxed bullets, I gas checked anything over 1400fps to prevent leading.  
With PC bullets in a pistol, I will push them 1800fps without a gas check isntead.
Hell, it's only in rifles that I am pushing them over 1700fps that I add gas checks to the PC bullets, due to the longer barrel/longer heat behind them instead.

I have used both. I started coating pc bullets using the HF electro- static gun and those worked just fine w/o the bases coated.

Since then I have switched to the HF red and shake 'n' bake because it is just s lot easier.  I can cost twice as many in the same amount of time.

I would have no problem going back to pc bullets with uncoated bases for pistol.

Some folks live where the humidly is high and cannot shake'an bake successfully.

Those folks use a PC gun.

Your shaking container must be a triangle around a 5 on the bottom to create the static for a good coat.

If you are fighting humidity - ditch the BB's and try this method.

I don't use this method exactly - I guess I'm a bit anal - I place each round base down on a AL plate covered with non-stick foil. I also use multiple plates and 2 ovens - one set for the preheat the other for final coat.

This does allow for full coverage even with the bullet standing on the foil. I also use gas checks on heavier loads.

Edit: - This is NOT me, just someone who found the sweet spot for pre-heating before applying coating.

Shake and bake is quick, easy and cost/material effective over spraying.

That said there are some pitfalls to watch for.

Humidity will wreak havoc on you.

Some powders will not dry tumble no matter how long , how dry or how hot the environment is.

Tweezers or spraying isn't my bag as I simply want effective function over form.

Different strokes for different folks

A simple 30 second shake with black airsoft soft bb's in a #5 plastic container is all I do.

I dump around 180-200 pistol bullets straight onto hardware clothe and into the oven they go.

HF red powder is ok and cheap, the other HF colors are horrible.

Tried preheating the bullets and found it to be an unnecessary waste of time, and a invitation to get burnt.

Some freshly baked .40


Some combo colored .45ACP



All done with one 15min bake coat, and I never touch a uncoated lead bullet during the process.

Ok, that's why you are having coating issues. Pre lubed bullets.

I've done some of that myself, and always end up doing 2 coats.

The lube is very difficult to remove with any solvent.

Your home cast bullets PC much easier.

If you are stripping off existing bullet lube here is an easy way.

Use large can, coffee, bush beans etc. Wash well, (I run it through the dishwasher.)

Fill half full with lubed slugs, add water till about 3/4 full.

Place on stove and let boil for 20-30 minutes. Add more warm water till mix is maybe 1/2" from top. Allow can to cool enough to handle, then place in refrigerator.

Later remove from fridge and break out hardened disk of lube. Pour bullets in basin and again wash with mild mix of hot water and Dawn dish soap. Be sure no small fragments of lube get into basin. Rinse with warm water and lay out bullets to dry.

This will remove 99% of the lube, a quick final wash with a minimal amount of Acetone or Lacquer Thinner will remove the last traces of lube. Note: Since most of the lube was already removed the solvent will be much more effective.

BTW - the lube can be given back to a loader and re-cast into sticks.

The lube may harden in floating clumps if there is not enough to cover the entire top of the water. On a batch of 115gr 9mm slugs with a single small groove I thought I had not run it long enough - but they were clean.

I first did this on some 45-70 slugs that had 5 lube grooves and the lube was soo soft it was like vasoline. I found that rounds left bullet up were melting the lube in summer and it was running down the inside of the case fouling the powder.

I was given about 4000 counterfeit plated 38 158gr SWC - thing is they were not plated, some jack@$$ sprayed them with copper rattle can paint then lubed them. The lead is very soft and even at 38spl min loads it gums up the barrel.

I intend to strip these and give them a powder job.

Don't think paint like enamel or latex. Powder coat is TOUGH, assuming you did it correctly and it adhered well to the bullet.

Use enough flair to get the bullet started, you don't need to really open up the mouth but you will need more than for say a jacketed bullet. Seat as you normally would.

You do need to be careful with how much crimp is applied. PC can get cut thru if you apply more crimp than you should/need just like a plated bullet. Of course, applying to much crimp is also bad with lead and even jacketed bullets. ANY bullet will be damaged if you go to far... it's really not different just because the bullet is PC'd.

Set up your dies correctly, you won't need to worry about damaging the PC.

Hey guys, I don't want to derail a thread, but I just wanted to ask some things about how exactly powder coating works.

Does powder coating replace a gas check on a boolit that other wise would need one? For example, this mold? Can I cast a boolit from this mold, powder coat it, size it, and shoot it? I will try to push these bullets as fast as is safe and sensible to do.

Thanks.

First, I ordered one of those molds when you posted that link a while ago. Thanks, was looking for a 6.5 mold.

I have not used the Lee sizer, but based on my research, they are what I will be using. I don't have the disposable funds for a dedicated lubrisizer.

So you powder coat the bullet, then you hand fit the gas check onto the base. Then you run the whole thing through the Lee sizer, and that's it? Ready to load, with no lube needed? What velocities are you able to obtain with your PC and GC 6.5 bullets?

This will be my 'go to' load for my Swedish brass that I've been so excited about, once I have my casting operation set up this summer.

Whether gas check goes on before or after PC depends on the bullet.

Some of my PC bullets won't allow a gas check on after PC as it adds to the diameter of where the GC goes.

So for most of my rifle bullets it's size/install GC, then PC and final size.

I don't have my mold yet and haven't ordered my sizer die or GC's yet. Mine will be fired in 6.5 Grendel AR.



Look close at the base of the bullet and you can see GC has been PC'd, then final sized.



My 44 mag mold is one where you can PC and then size/install GC.
3/9/2017 2:51:10 AM EDT

The above is correct. Gas checks before, after or in some cases can be done either way.

And Yes you can shoot many gas check base type cast bullets with just powder coating, but at the lower (or much lower) velocity range than you could aim for with gas checks.

There are some reduced loads for 223 that use like 5gr powder for 1800-2000fps

Cast bullets offer a new range of options - powder coating vrs traditional "grease groove" expands the options even more.  Then to add even another option is the free-chex made from beer or soda cans which is much thinner than std copper GC's and can be fitted to "plain base" non-GC profile cast bullets.

Now one factor that is often ignored is that the cure baking of the powder coat tends to leave the lead in a softer state than when my casting machine drops the bullets from the mold into a water tank for quench hardening. This means the benefits of running some of the harder alloys like Lino-type don't pay off as much with powder coat - but means that a gas check can be even more important to allow the soft base of the bullet cope with the heat and pressure during firing. This issue shows up when guys are trying to push 200+gr bullets out of 7" 300 blackout barrels.

As for LEE push through dies, slug your barrel then if LEE doesn't make the size you need buy the next smaller size and open it up. Google and Youtube can show you how, a wooden dowel and some 600 grit wet/dry emory cloth or "sand" paper. Can be done my hand on your coffee table in a few minutes if the die is close to start with.

I don't agree that you need to shoot "much lower velocity" with non gas checked powder coated pistol bullets.

I'm shooting a 440gr in my 500 S&W unchecked at a book 33,200 psi without any issues. This bullet is only 12bhn when cast. I haven't tested one for hardness after powder coating.

30,000 psi is no slouch in a 44mag it's only about 8k under maximum. (Cast bullet data) and these were only 12bhn when cast.

I have no doubt I could approach max cast data loads using the correct powder coated alloy in big bore pistols without using a gas check.

I understand that.

A good flat base bullet can be pumped up pretty good. What I was referring to was a gas check type bullet that has very little metal sealing the bore between the base and the lowest lube groove, the design is counting on the GC being present, and if it has been left off it is a weak point - by design.

The 440gr Lee that I use for the 500 S&W is a gas check designed bullet. Maybe there are some that have this problem you speak of but this one does fine.

I currently use 2 different loads. One I call the slow sledgehammer it uses 13gr Unique. The other one uses 27.5gr Iil gun.

Although I'm using them un-checked which many claim "hurts accuracy" both of these loads shoot nearly one hole groups at 50 yards and the Lil gun load has no problem staying on a 14x20 steel swinger at 225 yards.

So much for another cast bullet myth.

Does powder coating bullets replace the need to lube them before putting them through the Lee sizing dies?
