[QUOTE="dkhunt14, post: 1048290, member: 14053"] I am not sure about why it is hard. Usually Lapua is good brass and is annealed real good. Maybe it is because with the mandrel and turning it helped harden it. If not maybe your clearance between the neck and chamber is great and you get lots of movement when the brass fills the chamber upon firing and then when you size it back down. If you work brass hard it gets hard. It would be nice to know the chamber neck diameter and the loaded round diameter to see how much clearance you have. If you new who chambered it he should know. A lot of gunsmiths stamp the number on the barrel especially if it is a tight neck. Matt [/QUOTE]
