[QUOTE="rpierce, post: 2360456, member: 20643"] I realize you cant make it size smaller than virgin brass. However the bc die is sizing the brass more than enough to not get bolt clicks even after several firings and warmer loads. Im not getting a bolt click until there is a noticeable ejector mark. I did a powder charge test on a friends rifle and didn't get a bolt click until 3125 fps with a 245 berger and N570, 26" proof. At 3065 fps it shot a group well under an inch at 580 yds and no bolt clicks. That was with brass that had over 5 firings on it as I had it laying around the shop from sighting customers rifles in with. I have a N568 and 245 berger load @3025 fps in my personal rifle that just shot a group with .6"/.098 moa vertical at 580 yds. Wasn't concerned about the 3" left and right since it was a 15 mph cross wind. Doing a ladder test with N568 and 230 otms and the 5 gr spread is a half moa vertical group at 580 yds. At 3154 I started to get the first signs of pressure. Was a very slight click. Not even that noticeable. In my 338 norma improved version I had a 5 shot group at 580 yds with 1.1"/.181 moa vertical and a 300 gr berger at 2865 fps. No bolt click in the 26" proof. What more can a guy ask for LOL. Id say the brass size, chamber size and die size are all working pretty dang good. [/QUOTE]
