Primers should be seated a minimum of .002" below flush. If the primers go off on the second strike, this is a firm indicator that primers aren't being seated deep enough. A maximum depth for primer seating is about .007".

Is there a way to ensure that it is seated .002" to .007" during reloading? or i have to check it one by one?

thanks

primer seating depth is strictly by feel. You push forward on the handle at the end of the upstroke to seat the primer. You will soon develop a good feel for the amount of effort required.
