9 mm bullits. Powder coat? Or not?

Are they already greased or are they still dry. If they are still dry and you are going to shoot them indoors I would PC them for sure, It they are already greased and you will use them outdoors then shoot as they are...probably no discernible benefit to going thru the "degreasing/cleaning before PC routine" for outdoors use.

I still have to run them through a sizer die. ( which I’m still looking for).
I’ll be shooting outside.

I’m just guessing it would be less cleaning,with PC
 
As Fingers said, if they're not already lubed, PC and size. I use a Lee .357" push through die for my cast 9mm bullets. Inexpensive and fast. Western Metals has them in stock for $35. If they are already lubed cleaning it off is not worth it.

There is an article on bullet coatings in the 2016 or 2017 Gun Digest.

Uncoated bullets were faster when all used the same powder charge.
 
Dump the lubed bullets into a tin of acetone, rattle them about and then dump the acetone into another tin through a strainer to catch the now de-lubed bullets.
Then PC as normal.
If the bullets are hard waxed, heat them on a heavy duty paper towel to melt the wax away and then clean them in acetone.
 
I might PC 100 and run a test to see which version was most accurate. For shooting outdoors, accuracy is everything.

Indoors, the smoke for the bullet lube of uncoated bullets might be an issue. It does not bother me in a well ventilated range, but if we are shooting in the dark with a flashlight, then the smoke is a huge problem. I use plated bullets for that.
 
These are not lubed yet. Fresh out of the pot.

I’ve got to size them myself.

So I’ll probably just buy a sizer die and some powder coating.

PC does the same thing moly treating does - reduces friction. Reduced friction = less backpressure. Jacketed bullets "usually" produce higher velocity over cast lead bullets for the same reason.
 
When I checked my PC bullets against their traditionally lubed counterparts, all else being the same, the PC bullets were 10-12fps faster. That was in 9mm and light .357 target loads.

Buy your LEE sizer from Higgenson powders in Hawksbury for C$27.50.
Buy "tool blue" PC powder from Emerald Coatings in Palmerston. It always works.

Powder coating bullets eliminates the chore of lubing, and creates a very hard encapsulating shell. Since the base gets PC'd too there is no lead vaporization there.
 
If your shooting indoors, would be nice to powder coat them to keep the smoke down.

Everybody I know that shoots a Shadow I/II/ 75 TS all use powder coated bullets.

If you were around during the molycoating craze 10-20 years ago, you might have experienced this. The moly-coat reduces bullet friction and the bullet begins moving down the bore ealier and with less pressure. Initial pressure is lower and so is peak pressure - resulting in lower velocity than the same load using an uncoated bullet. To get the same velocity with the non-moly coated bullet we actually had to use more powder.

Powder coated bullets are slipperier than regular cast bullets, with a lower friction coefficient. If you ever tried sizing PC bullets, you would have experienced this. The PC bullet is remarkably easier to size than the same bullet without the PC.

Hopefully that helps.

So how would the PC bullits compare to berry plated bullits.
Right now I’m using berry 124 g over 5.1 CFE.
But I’m going to switch to PC 125 g bullits.
