I use the black plastic bb’s, but I like the idea of styrofoam pieces.Go to ArtfulBullets.com or Castbulletsassoc.org, or Castboolits.gunloads.com. There is a wealth of information and help there. For some advice, look for a used toaster oven to powder coat your bullets. I found mine for free when driving through a neighborhood during trash day. A woman was throwing it out. Be sure to use #5 recycle tubes to shake your bullets and powder to build the static charge that holds the powder to the bullet. Shredded cheese tubs work well for me. I don't use the rubber bbs as suggested by some. Instead, I use styrofoam cup pieces. Not all powder paint is the same. Eastwood.com is one source for powder paint. To me, Harbor Freight powder paint doesn't adhere to the bullets well. I found most of my paint at a local powder coating service. Sometimes they gave me powder paint and sometimes I bought it at a lower price than Eastwood. I have a lifetime supply of powder paint now. Some of the paint works great. Some doesn't have an even color but works. One such color is white. So, I PC my 38-148WC bullets with them. After I shake my bullets, I pour powder and bullets over a screen. The powder falls through the screen onto a newspaper. I then fold the newspaper and pour the paint back in the tub. I pour the bullets onto the aluminum lined tray. I've had my best luck using non-stick aluminum. to bake my PC bullets on. I have tossed my hot bullets into water but am considering just rolling them on a newspaper covered concrete floor so the paint can flow out. I hope this helps.
I use tweezers to position and pick up PC bulletsI use the black plastic bb’s, but I like the idea of styrofoam pieces.
My toaster oven was $10 from a thrift store and looked new.
I use the purple surgical gloves as they seem to not attract the paint when I touch the bullets.
Basically, my method is slightly different but you’ve written out the start to finish directions pretty succinctly.
I am new at casting & powder coating bullets. please tell me more about antimonial growth. does antimony expand with age? or if too much is in the mix?yes.
a month at minimum, but for stuff i care about i let them go 6 months.
the reason i do that is so i can monitor the age hardening AND the growth.
i've been caught out by antimonial growth before and walking back to the truck then driving home to knock out a bullet from the barrel is not how i like to spend my opening morning.
Good idea.it doesn't make the lead harder it traps pieces of antimony in different parts of the bullet.
this gives you a harder reading on a BHN scale.
hopefully that made sense.
as to letting them sit before coating and cooking.
it's probably not necessary.
when you cook the bullets to cure the powder your actually drawing back the hardness.
the way i cook mine is a little bit different than what most others do.
i bring my oven up in three stages.
the first is to 325F and i hold it there for about 15 minutes.
then i take it to 375 for 20 minutes, this is the 'wet' stage of the powder where it flows and smooths out, kind of like self leveling paint.
then i take the oven up to the full 400F and hold it for a full 20 minutes when it gets there.
when the time is up i turn off the oven and watch for the temp to drop about 5 degrees.
then I take the tray out and dump the bullets in a bucket of water.
what this does is give me a full hour of soak time [necessary to quench] and a consistent batch to batch hardness regardless of whether i air cool or water drop my bullets initially.
most others don't water drop or care about time other than the 20 minute cure time.
