Note to self

[Wolfdog91]

Welp , not to self, 6.5 mm deep hollow points dont do too well in the power coating oven on higher temps like their bigger .316 cousins.... Was only running hem at like 360° after getting the paint flowing....ugh they where sized and gas checked to ....o well , was hoping to run them through the AR later today but what can ya do

I think I would get a thermometer for that oven. Just to make sure.

[Wolfdog91]

O it's got one was reading 350 when I went and checked

put your hollow points upside down on a nail, the powder coat wont collect inside the cavity and they bake better

I overbaked some 277-135 to where they were bent once. Now I’m using an old convection oven with a timer.

OOPS !

If at first you don't succeed ... lower the temperature !

They look fine. Just load em up anyway. Now you're going to get to enjoy a real treat - whenever I have screwed up some powder coated bullets and had to toss them back into the pot, you get that wonderful aroma of burning carpet and home perm wafting through the area. Oooo it stinks! Well, look at the bright side; at least you didn't have this problem on a 100 round batch.

That sucks. I am no expert but it takes a bit of heat to get that result. And 360 seems too low.

[Super Sneaky Steve]

That oven wasn't 350. I cook .22 cal boolits all the time at 400. Lead will not melt at those temps.

Most small ovens are all the way on or all the way off. Make sure you pre-heat and your cycles don't go too long.

[Dusty Bannister]

I only see a small amount of bullets in that damaged batch. I am wondering if perhaps since the oven is set to run at full off or full on, there is insufficient mass to accept the amount of heat you are producing. Maybe adding some ingots to act as heat sinks would make a difference. I am thinking that we already have shown that as a casting pot gets lower, the temp of the alloy gets higher, even though the pot cycles at the same rate. Maybe the small number of bullets shown in the photo is misleading.

[Sandspider500]

That oven was hot.

[beechbum444]

oven has hot spots......put a cheap 1.00$ tray/pan on the top shelf to shield the direct heat, I agree with one of the top post....360 degrees did not do that

[THE_ANTIDOTE]

I cure mine at 450 to start for 10 minutes then down to 400 for 15 or so and have never melted any. I even bake mine with masking tape on at the 450° and nothing... I posted here in coatings and alternatives how I had dropped a bullet in my little oven and baked it for 3 consecutive heat cycles at 400° +, all that happened was the powder coat turned smooth like glass/clear coat. My bullets are just about all lead. Just for your and your family's safety, you may want to check your oven as others have stated or at least don't leave it unattended while you cure your bullets. Good luck, hope you find a solution.

Maybe run your Easy Bake oven with a PID?

[jsizemore]

Could be they are too close to the element/s. Convection fan ain't circulating?

[sukivel]

Those little ovens are notorious for uneven heating.

Had my PC oven set perfectly but bumped the thermostat while moving it. On the next PC attempt I found several lumps of colorful molten lead on gas checks.

It was a real tragedy.

Little ovens typically have the thermostat outside the heating portion causing outside temperatures to affect like when the Little oven that could sits next to an outside door in the winter and someone keeps running in and out.....location makes a lot of difference!

This works real well with the PID attached. And I don't knock over any rifle bullets.

Popper is this a tile on a hot plate? I have considered heating bullets from the bottom. I do heat bullets from the bottom when I am filling hollow points with hot glue, especially the softer varieties I feed the glue into the hollow points in tiny pieces. It slowly melts and air bubbles rise to the top. Touch the bubbles with a sharp tooth pick and they pop. Not for everyone, but I enjoy the process. I fire hollow point pistol ammo into stacks of dry telephone books as that causes many hollow points to fail to open. I could never the a Black Talon to open. They opened fine in water jugs, but dry phone books are a real challenge. My Federal's 45 ACP 230 grain Hydrashok only opened about 50% of the time. I wasn't all that impressed with Hornady Critical Defense either. But hot glue filled hollow points opened 100%. Never fired them thru drywall yet, but I am confident they will open. I suspect if I filled JHP's with hot glue it would ensure they open as well, but I have not tried it yet.
