Once fired brass sizing

[Cammy]

Bought a bunch of once fired Norma .270 WSM brass. Should I full length resize with a should bump before reloading in order to fire form to my rifle? Is neck sizing enough?

Does it chamber? Personally, I’d resize to be slightly smaller than your chamber.

I full-length resize every time for a hunting rifle. I'd rather know for certain the round will chamber in suboptimal conditions than try to eek out the extra 0.1MOA you might gain by neck sizing only.

I certainly would not rely on neck sizing for brass that not been fired in your specific rifle's chamber.

+10.
In my early years of hand loading I got into the neck sizing trend. I found over time my 300 win mag brass was getting wider somewhere closer to the base. This lead to it not chambering at one point. When i ran it through my full length sizing die, it started to scrape brass off of it. I stopped neck sizing after that. If there is a precision increase, my rifle does not need it.
