[QUOTE="AZShooter, post: 1024971, member: 5219"] Based on the thickness of Lapua brass, I would bet you will be turning your necks. Here is a good article to read on the details of neck turning: [url=http://www.6mmbr.com/neckturningbasics.html]Neck Turning Basics[/url] I would consider the .003" difference as the minimal clearance you would want. That is only .0015" neck clearance per side! I tried to find some data on what others are using and so far haven't found much. I have a 6mm-284 reamer for no turn with Lapua 6.5-284 brass necked down. The reamer neck is .277" The neck clearance is .004" I use a .272 bushing for a .001" neck tension. This has worked out well in three rifles which are repeaters and used for hunting. Once you have your necks turned you will have to use a bushing die (or a custom die) to achieve the neck tension you want. I would suggest using a bushing that reduces the OD of the neck by .001" and .002".
