Acetone may be the best solvent to do a finish rinse, prior to powder coating...

Okay so count me in for this method...

Looking good. One comment on your pics of the bullets in the tub - up to a point, it works better with more bullets than that. I'm using about the same size tub, and usually do 50-100 bullets at a time. Having them packed together seems to pack the powder onto them better.

I don't worry much about the after-sizing diameter, although you may be applying a bit more powder than me, I only do 2 coats. Your particular powder may act different than mine though.

Thanks. You are absolutely right, I did about a 60 bullet run last night and used the same container, with a little more powder, and they came out coated MUCH more evenly through the first and second coat, a fine observation you've made.

WWWEEELLLL plan B was a bust ( what a mess )
SO on to Plan C - should of done it this way after Plan A anyway.
Shoot all the rounds I have the way they are and order my Cast heads unlubed.
Yes Shadow I'm using the 150's HPs in my sons short and weak M&P I don't plan on shooting anything lower than 180's in my 10's.
I did find a guy in Ga who does cast 180gr HPs - ( they look like your 150 HPs Shadow ) who doesn't mind not lubing them, so I'll start with him.
Mean while I have 1000 200gr HCFP to use up and 500 220gr HCFP also - HMM I need more brass.
O WELL more time at the Range.

Ps... The Blue Press ( Dillon ) is handling SNS coated HC bullets. Hmm a new trend starting in the cast bullets.

PM me, I have some.

Loaded up some more powder coated bullets last night, figured id share the pic  When I'm loading them I have my barrel laying there to check the fit in the chamber and I've discovered that I'm having to shorten the Over all length to get them to slide in and out of the chambers smoothly. I'm near certain this is because the Powder layers up pretty good on the nose portion of the bullet when tumbling. The cases have been push-thru sized. I figure shortening the OAL by just a hair is okay becuase I am using starting charge weights for the load and have been seeing no pressure signs.

Any one else experienceing this with their Powder coated bullets?

Yes, anything that makes a bullet ogive larger can result in the front of the driving band being farther forward after sizing. This is more true with a rounded ogive of course, and one reason I prefer a small step down at the front of the driving bands.

You are right to seat your cast bullets as far out as possible, to fit your chamber, but yours are seated out pretty far in that pic anyway, so I wouldn't worry about needing to reduce the OAL a little.

Plan B - revisited - I used a super hot heat gun I've got for plan B - so I wouldn't mess up my oven. Now I'm I going to use the oven.
I thought about the ones stating their ovens wouldn't get hot enough with out turning them all the way up Hmmm ok I turned mine up to toast and put the bullets in for 10 min. Went out to check them 10 min later and my bullets where gone I guess toast meant toasted - pulled the pan out and there was 2 puddles of lead in the bottom under the screen  - I like to fell off the stool laughing   - so mine gets hot enough.
I'm now finishing up the last 440 bullets at 400deg and now to figure out what degree sing solution I going to clean them with?
Once I'm done with the other 1500 bullets I won't have to go through this again. It only took me a about an hour or so to do the rest of the 440 bullets after the melted ones.
OOOwell it was raining and I didn't have anything else to do today.


Doug

The old expression Live and Learn comes to mind here!   

Post Toasty!  Bullet Roasty! 

I was cleaning up the oven just a little while ago - and pulled the alum. sheet out of the pan to catch the melted lube and noticed that their wasn't enough lube there to account for all the bullets I delubed - I figured it out when I cleaned the walls of the oven, it had vaporized alot of it and thats why the bullets and the oven walls where tacky - oven cleaner - what a mess - the next batch I'll try 200deg and 15min, maybe that will work better and cleaner

Doug

That's funny about the bullets melting.  bummer though

Yeah, 200-ish degrees should be plenty for just getting bullet lube off. I don't know offhand what the perfect temperature is, but I do know you can melt the lube without any smoke or burning, if you keep the temp low enough.

BTW, you'll want an oven thermometer when you start powdercoating, if you're not using one already. Don't just go by the oven dial.

What does lead melt at - 800deg
Doug

No, much lower. Depends on the alloy; wheel weight alloy melts a little under 600 degrees, and some type alloys melt in the mid 400's.

Well - I degreased  them - went to HomeDepot and picked up a spray bottle of Krud Kleaner to try - Worked Great - poured it into a plastic container and let them soak for about an hour - dipped them out with a spoon and rinsed  them in hot water - TA DA - perfect. Coated my first batch of bullets in a Deep Purple Red and cooked them at 400deg - 10 min - No one said anything about them sticking to the screen, anyway second coat and done and then sized them. Beautiful!!!
I've only found 2 companys that will sell me the cast heads unlubed - out of 5 I e-mailed.
Yup Yondering good tip - bought an oven temp gauge.

Doug

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.

Doug

Doug, The small digital scale I'm using is a Frankford Arsenal from Midway USA $29 on sale.  It has some draw backs but I understand those and work with that.  Only even numbered tenths of a grain  0.0, 0.2, 0.4, 0.6, 0.8 and it will drift easily.  That's why I take multiple measurements with it.  The best part is it agrees with my balance beam on the even tenths.
