I can almost guarantee you it is the paint you are shooting. Try some high quality paint and you will notice a difference.
If you are using high quality paint, you can try a smaller bore barrel back. The stock Etek4 barrel is a .693 and therefore will be fairly large for majority of paint today causing the inconsistencies. Seeing as this is an Etek4, I'm assuming it's fairly new, so the regulators or orings should not be wearing out just yet unless you've put 30+ cases through it. Make sure your dwell setting and your LPR setting are on stock.
