Re: New to once fired
Once fired brass will have a slightly higher case capacity, so its possible to have a small difference in performance. With that said, I have never noticed any difference between neck sized or full body sized reloads, in performance, accuracy, or point of impact. But its hard to say in your particular rifle/load combo. Best thing to do will be to try it out. Load up 10 identical rounds except Full body size 5 rounds and just neck size the other 5 and compare.
