I'm just getting started in reloading. I seated primers for the first time using the Lee Challenger press.

I measured my primer seating depth and compared it to the depth on factory loaded ammo. It turns out my reloaded primers are seated at double the depth of the factory seated primers.

What is the maximum seating depth for primers? Will my double depth seated primers work as is? Can I remove the primers and seat new primers, or should I just throw out the cases altogether?

Background info: Cases are once-fired Federal American Eagle .30-06 M1 (150 gr FMJ with reduced velocity). Rifle is 116 FCSS .30-06. Cases have been neck resized with Lee collet dies.
