[QUOTE="Mike Matteson, post: 2775111, member: 101791"] The other is I would think that a crimping die would change the tension that somewhat. Creating more tension. In reading here, the grouping tigthen up more. Just how much I don't know. In reading the neck should be 1 caliber length of bearing surface. By holding to that amount of bearing surface creating tension it's in away reduced the tension at the same time compaired to the full length of the neck. I was reducing the amount doing this a long time ago it improved my grouping, and have stayed with that by using neck sizing dies only. Setting the length of the neck being sized. That was mostly belted mag cases. At that time I used standard RCBS neck sizing dies. I didn't have clue why. I felt at the time that the alinement of the neck not being size all the way to the shoulder held the case in place better. My groups were better. I didn't try much else. Now that's a different story. I have been changing out my reloading equipment a ($$$) huge amount over the last plus year This is not the place to come to, without going down the rabbit hole. 🤣 🤣. I have to laugh at myself. It's been enlighting, changing my ways and others it just reinforced it. "GREAT DISCISSION" [/QUOTE]
