Adv. Of powder coating:
Smaller initial investment over buying a sizer lubricater.
Minimal xpenses for future coating
Bullet diameter can be increased over mold diameter( if as cast is not big enough)
Lead alloy/hardness not as critical
Pretty colored boolits
If bullets are stood up on end bullet bases are smoother.
DISadvantages of PC
Longer process time over my Star lubrisizer.
Adv. Of lubing
Quicker than pc'ing
Different lubes can be used
I have found no better or worse accuracy in either process.
