So I'm fairly new to reloading, and right now am mostly working on developing a load for my 6.5 Creedmoor RPR. My brother-in-law who got me into reloading advised me that for best accuracy, I should shoot factory ammo, save the casings, and then neck-size only, the idea being that the brass would be fire-formed to the chamber of my specific gun, which means in would sit more consistently in the chamber and thus increase accuracy. But since then I've also heard things where people are saying that neck sizing isn't worth it, or that in can even be less accurate than full-length sizing.
Does anyone have any advice in this regard? I plan on testing out the same load with some neck-sized only cases and then the same load in full-length sized cases, and see which one performs better, but I'm curious what you all's experience has been.
