I dabbled with powder-coating in my XP100 30BR & 7mmBR plus my 357Mag revolver.
I needed to re-size ( Lee push through) after powder coasting or I couldn't chamber in the revolver as the powder coat fattened the bullets too much. There are companies like NOE who are making bullet molds slightly under-size to sell to the powder coat fraternity.
Certainly makes cast bullet shooting a lot less messy with no bullet lube/ lubesizers / etc.
Accuracy I can't comment as to whether it was better, but it wasn't worse and the bullets looked "sexy" .
