I have been purchasing some 9mm 115 grain powder coated lead projectiles to begin loading my 9mm Luger pistol. Now that I have worked out a load that works well, I purchased a cheapy 125 grain LEE mold to try out casting for the 9mm. Looking at the purchased powder coated projectiles, it seems that the powder coating is very uniform. What affect does powder coating have on bullet balance and how do you coat your projectiles to attain this uniformity?
