Casting and Powder Coating 9MM

Like many before I have casted, gas checked and lubed many a bullet over the last 8 yrs and they all performed well...but it was a real PIA for GC and Lube process.

About 2 months ago I ordered all new LEE molds for .224, .356 (9MM), and .30 cal (308, 30-30, 30-06), got me some Princess Auto Blue/Red Powder Coating and Toaster oven. Havent had much time to do much other then (9mm and .223) and finally got the 9MM coated and completed.

The process of coating and baking at 400F is so much easier and I will making these PC for about .08 cents per round.

Loaded up 100 rds of 9MM, 124gr, with different powders for ladder tests (10 each)
Clays 3.2, 3.6, 3.8, 4.0 (Max)
700X - 3.2, 3.4, 3.6, 3.8 (max)
Vitavoria - 3N37 3.4, 3.6

Once I can get to range will report results

Picture is cast 9MM against with Campro 124gr FMJ. Finished weight is between 123-126grs. turned out really good in blue, great coverage.

Have you miked any significant change in bullet diameter with and would wonder if this process leaves any build-up in the barrel?

Those do look great shake and bake once?

Sawbill Once you run them through the size die they are ready to go.
They do not leave anything other than a bit of white powder in the barrel.
Line 052 - looks great and good luck!

Just once, #5 PET cool whip container, the blue seems to coat better then red. Before coating, I soak and dry in acetone to remove all residue

I was at princess auto today grab bottle and of the blue.
Not sure when I get to baking some. But did you stand yours all up have you try just dumping on grate screen ?

No change, the mold is .356 consistent, I resized using the LEE .356 dies before and after powder coating.

I got the blue and red powders. I am finding the blue coats better and more consistent then red. Did some (100) ladder loads with different powders for the .223 this week, hoping to get to range this weekend...unless MikePal invites me over....hint, hint...
