Bullet seating inconsistencies

I have loaded about 500 .308 rounds so far on my 550C. Was getting fairly consistent seating depth but am now getting variances of .006 +-. I am loading these one station at a time to maintain a handle on the process. Cleaned the entire shelplate and reassembled as per the instructions and retested - still no consistency. Die is snug. I have read everything I can on this press, it’s quirks, and how to find the groove with it. What am I doing wrong? Bench definitely needs to be anchored as there is play. Die could be cleaned as well. What else can I do as this is an impass for me at the moment. Thank you

If you are using lead tipped bullets you will always have variances. Even with plastic tips you might consider a comparator made by Hornady that measures on the part of the bullet where full diameter begins (ogive).

I am loading Sierra MK 168 BTHP. I am getting those variances with the comparator. Sorry I should have stated that. Thank you

Measure just a few projectiles using the comparator. You won't have .000" variation from one projectile to the next. .006" is very minor.
