I forgot to mention when I sized mine that some where Hard to size (thick coating? ) got me to thinking has anyone thought to weigh their heads to see if the is a noticeable difference in weight?? My scale doesn't go high enough - by the way Shadow - what type of digital scale do you use for your pull downs . it looks like just what I need.
My next batch of bullets, I'm going to use a Teflon coating I came across.

Before you start adding other coatings, polish out your sizing die. (Assuming you're using a Lee push-through die?) Those Lee dies are all rough on the inside, and polishing is a requirement, not a recommendation, IMO. It's not hard to do, and makes a huge difference in sizing effort. It is also a lot easier on the powder coating when the die is polished, and you'll get better results overall.

If you're looking at digital scales, the Dillon is the only way to go, in my experience. I've had iffy results from most of the other brands, but my Dillon has been spot on for over 10 years now. They do cost more, but you get what you pay for in this case.

BTW - using the term "heads" for bullets makes me think of clueless liberals, who think a "bullet" is the whole loaded round. Most people who understand guns know the projectile is called a bullet.

You may not want to use teflon, it's been mentioned that it can produce poisonus fumes at high temperatures. I think Yondering posted about it earlier on this very thread. Use caution! Just figured I'd throw the heads up, I'm not a chemist and don't know much about Teflon so take it for what its worth.

It's good to hear that the powder coating is working for you given all the trouble you've gone through LOL! Post a pic if ya can, I wanna see the deep purple red 

As far as the added weight I know from my lee 175g .401 TC mold using straight wheel weights air cooled, with 2 coats of powder they weigh ~177-178g and from my lee 125g .356 2R 9mm mold they weigh ~126-127g using same alloy with 2 coats, weighed on the RCBS 505 balance beam. I'll weigh a couple uncoated ones tonight and get back with ya.

The Teflon Coating I'm using is being done outside. The MSD says nothing about posionus fumes.
You know why they call the cell phones Smart Phones
Because they make people like me look like IDIOTS I was perfectly happy with Smoke Signals - I'm having my Son set me up on his personal server to put my photos on to upload - when he gets around to it anyway.

I just picked up 3 coated and 3 uncoated of each caliber at random and weighed them.

.401 bullets uncoated: 177.4g, 177.5g, 177.8g
.356 bullets uncoated: 127.5g, 127.3g, 128.0g

.401 bullets 2 coats of powder: 178.0g, 178.5g, 178.4g
.356 bullets 2 coats of powder: 129.5g, 129.5g, 129.4g

It's not really scientific, you'd get more accurate if you weighed the same bullet before and after coating it. Take this info for what you will!

Thank you BT8850 - I didn't think it would be enough to worry about - but it stuck in my mind till I could now for sure.

Doug

Bump - need to keep this up front for reference.
The Teflon is turning out out to be a pain to work with. Well at least I haven't melted anymore heads.

Doug

Man what seems to be the issue with the Powder Teflon Paint?   
Is it being temperature sensitive? 
Not adhering to applied surfaces?

Doesn't adhere as well as the others. I'm going to try something different - since I'm only going to use Teflon coatings on the 200 and 220 gr heads - I going to use an extra step - these loads will be on the high high end for the Mech-Tech and possibly the G20 6.6" barrel.

Doug

Taken me a couple years to come back to this. But Im here now!

I am experimenting with some soft slugs at top hand gun velocities W/O a GC for max expansion...





Doing them in the 10/40 as well..

We will see...

One of my last reloading sessions, I decided blue on silver looked pretty cool. Here are both 10mm and .40 cal. (Ended up with 253 in a box of 250 I bought)

CW, Your bullets look great.  Did you use a slurry method to coat your bullets? 
If yes what was your liquid carrier...Acetone? MEK? Other?

I haven't jumped into the deep end just yet.    I bought these form lucky13 bullets.

Local friend of mine tried several methods and the best results by far were had using a plastic container with a handful of airsoft bbs and a few ounces of powder dumped in, he fishes them out with some forceps and then bakes them on a cookie sheet.

RW, it seem your friend is using the powdered paint dry with no solvent?

Should have said that, forgot.
He is using regular powder coat material, I forget where he got it but many places sell it online. Just make sure its a good brand and not the harbor freight junk. Both are ground polyster resin but the harbor freight stuff is garbage.

I know the parent company to cerakote is a premium supplier, it should run about $15 a lb.. one pound will coat many thousands of bullets.

Even better..under $4 a lb for their discontinued stuff

There is no leading with this and no sign at all of the powder coming off in the rifling, in fact the powder is 100% intact on most recovered bullets.
