[QUOTE="Mike Matteson, post: 2637127, member: 101791"] I fully agree. I not saying to trim the case way back. I did at one time, and let them grow to where they were to long. Then trim again. So my brass were all different lengths. I hadn't realize that is was causing me problem or possible problem. Now on my Peterson brass (New case right out of the box) they varied several thousands overall length. So I used the shortest dimension, and cut my brass to that length for consistency. (5). The other is I cut my brass for thickness. So they have to be on the money to start with in length. They won't go into the chamber until that done. I still have to fireform them. I'll see what the growth is. Anneal them and size them, Check and see what I have then. What kind of growth I have to the shoulder, and overall length. I only have 3 cases fired presently. The neck area is still tight. so I'll have cut another 1/2thousand off the neck. I'll be at .0125 instead of .013. If that doesn't work, I may reduce to .012 or send the reamer to reshape it. I think where I missed it at was the .243 is really .2435. [/QUOTE]
