I have a Savage 11 Trophy Hunter XP in 260. I'm new into everything and have been full length sizing every time. I only have one gun. Should I be adjusting my die to only size the neck? If so how do I do that?

I'm using Norma brass currently and I think I have resized 3 times full length. Maybe I should only be sizing the necks. I'm not shooting too hot of a load and have not had to trim length yet.

Should I invest in the gauges that tell you how close your shoulder is?
