Thread: Neck sizing

I’m currently neck sizing some brass which iv never done before and when I chamber a sized piece of brass the the bolt is firm to close . It doesn’t need to be forced but it is firm. My guess is that this is normal as the brass has “fire formed” to my chamber and I’m simply sizing the neck no shoulder bump etc etc so the firmness I’m feeling is the rest of the case tight in the chamber?

Something I’m not familiar with as I usually set my F/L sizer in micro adjustments until the bolt closes with ease on the empty case (little bit of shoulder bump)

F/L dies are currently unavailable

Many thanks
