Help with neck trimming. I'm going to have to purchase a good bit of 7LRM brass or else neck down my own .375 Ruger brass to make my own for the 6.5LRM. Any way I do it, this will require neck turning. As I look more and more into it I'm torn as it's looking like outside turning is the most common method with the inside reaming being the more precise. Any downside to the internal reaming vs external trimming? Thanks.
