simple Hi-Tek coating

I am still amazed at just how smooth they size too, the lee ones i can feel every machining mark when hand sizing, the carbide are so smooth.

What's this "Hand Sizing" thingo???

Some are mongrels to size in the machine, so they have to get sized by hand, 100 SWC make my machine and me very sad. It mangles more of them than it actually correctly sizes.

Agree... the 105SWC are a pain in the coit through the Magma sizemaster. Even my home made sizer hates them.
I run them through the Lee APP with a Mr. bullet feeder doing the collating.

don't swirl for too long. Dump them a bit wet.
try pre-warming them before baking. they will be smooth rather than rough like in the pictures

Does this texture present issues for loading and shooting?

In short, no. Sizing will smooth out the mating surfaces.

[Ausglock]

The rough texture may indicate poor bonding to the alloy.
Do they pass the smash test?

Lets see...

Oh really? I will have to have a serious look at your machine, how the SWC bullets drop into the sizer etc... Its it just light weight eg 100 grain or does it do the same with say 158 swc?

Finally got off my bum to make some tungsten carbide Lee App dies for myself and a mate.. Made 0.3755, 0.4585, 0.3560, 0.5107, 0.4517, 0.3087, 0.3583. 0.5010. Will be making more for 357 and 44 mag. Attachment 288826

They look pretty flash. Reckon they would go well with my sizing machines.

I'll post pictures of the care package I get yesterday. They would be ideal for your machines jatz.

M.a.d if you're up next week, check out what it does. 158 swc are ok, it's an issue of then not exiting the sliding bar. Ideally the punch should push through the hole, but mine is not setup to do that....

Well, the new bonded mold release really makes the slugs drop easier from my 8 cav MP molds, but there are some wrinkles on the boolits. The molds are new, and maybe they just need to be run a few sessions to break in, but I'd like to be clear on just how heavy an application of the release is needed. I used a small artist's paint brush to apply the release, mixed in acetone at the concentration recommended. After drying the treated mold surfaces were dulled a bit, and the black finished underside of the sprue plate had a slight but visible gray film. The cavities had a few black deposits where the release pooled a bit. Too much?

[Ausglock]

Probably should have seasoned the new mold first.
Once the product has been treated and heated, just give the cavities and spruplate a light brushing with a toothbrush before casting.

Thanks, Trevor.

Been a bit quite on here lately.

Just cleaning up my bench and though I'd share a photo of some of the projectiles I have coated and tested.

[Ausglock]

Yeah... Just casting, coating, baking, sizing, boxing and selling.
