Re: Does new primed brass need to be resized?
Yes you should resize all new brass even if it is primed. I compared new resized brass and just factory resized and the difference is noticeable. When you take the time to resize it the bullet fits more snug in the case. Try it for yourself and you will see. The factory brass will allow the bullet to be seated much easier then the brass that you take the time to resize. The sizing difference will have an affect on accuracy.
