It seems neck sizing only is becoming a thing of the past. I just ordered some Redding full length/neck sizing dies. I am curious how much change I will see?
With neck sizing only, my Lapua brass lasted about 9-10 shots. I just had to retire about 90 cases. They were starting to separate.
In theory your brass will not last as long and you will need to trim more frequently. The reason being of course that more of the brass will end up becoming worked more fully than neck sizing alone where the bulk of the brass is already fire formed to the chamber. Lot of variables are going to affect that not the least of which is the caliber, chamber spec, the quality of the brass, frequency of annealing and how hot the load is.
