Powder coat thickness

[Paul101]

I’m casting my own bullets (.45-70 350 gn @.458) and I’m wondering how much the powder coating will increase the bullet diameter before I size them.

Thank you

This is going to sound really flippant, but it depends on how thick you coat them.

I cast to throat size and then coat, leave a week and then size and lube.

I just wondered if the increase to diameter was in the region of .005-.008” per coat.
I think its a weekend project in the man cave.

When I powder coat for shooting a light coat usually gives 2-3 thou increase , So after casting I size then powder coat and then resize to final diameter.

Excellent, just the sort of info I’m looking for.
Thank you

Could I ask where you get your powder coating powder from?

Thanks
