PRIMER SEATING

IS THERE A WAY TO ADJUST DEPTH OF PRIMERS BEING SEATED?

Provide more information to the problem you are having.

If you are not getting a full seating of the primer, then check the shell plate to make sure it is not too lose. Or make sure the primer seater assembly is fully screwed in and slightly tight. Check that the primer seating post if extending fully above the bottom of the shell plate. I have seen issues where enough dirt/dust particles have gotten below the post and prevents a full extension. Lots of pressurized air to blow out the dust to clean.

I have yet to see a case where a primer is seated to far if smooth pressure is used to seat the primer.

In short I know of no way to adjust the primer seating other than proper setting of the shell plate and keeping the seating assembly clean.

Primer seating depth is not adjustable, it is done by feel. That said, there are factors that affect how deep primers are seated. lcb did a fine job of covering them.
What caliber, and case headstamp are you having problems with?

One other thing to consider, and everyone may already be aware. Some .308 Win/7.62, 9mm, and .223/5.56 can have a military crimp that needs to be, or should be removed. If you are having difficulty seating primers. This could be another problem.

It is easily solved with a couple different methods. Reaming or swaging. Dillon has a swaging tool I have never used. Many people swear by it.
