[QUOTE="Rhovee, post: 2172718, member: 101820"] Kris (highdrum) is correct. Min SAMMI is .551 on the .200 line for the RUM family. If you held the reamer .094 shorter, you would end up about .5495-.550. I have had some MIN SAMMI chambers with clicker issues. Mostly due to die's not sizing enough, and tough brass. I went .001 larger at the base to help prevent clickers and allow the factory dies that are cut .094 to work properly. My (3rd) fired cases are coming out at .5495-.550. Sized brass is coming in at .5475 of the .200 line. So we are getting .002-.0025 sizing at the web which is perfect. I have gone up to 91.5 grains H1000 and 230's with no signs of pressure. Being 2 grains under that for accuracy is great. Brass will last a long time and H1000 is great on barrels. [/QUOTE]
