[QUOTE="rcoody, post: 1099598, member: 91090"] sounds like you are doing really well. that 400 yrd group is awesome. you certainly do have a sub moa gun as for neck turning. It is a pain and unless you have a gun that you are trying to get into the 1's and 2's not worth in. Get you a case inspector. With that you can measure neck thickness and pick the brass with the most uniform neck thickness. save that for your accurate loads. neck tension is very important. that is why I would love to neck size that ar brass. I check runout a lot. You check brand new lapua brass and it is about perfect. Check it after full length resizing and with my coax and forster match dies I am around .002 already. then after bullet seating with my forster micrometer dies it varies from .002 to .004. I use the .002's for accuracy and just shoot the others. accurately measuring powder is my most recent step with real results. I measure powder to .02 grains and SD's drop into the single digits and vertical spread disappears. [/QUOTE]
