I think powder coating makes up for the Lack of interest by many shooters in actually measuring throats and grooves, and spec'ing a mold to fit, lack of controlling Brinnel hardness of the bullet alloy to match the load pressure, lack of adjusting load pressure to the alloy hardness...result in poor performance on target.
I'll admit this is me to a "T". Maybe when I retire I'll have time to fret those things. right now I prefer to spend more time actually shooting.
