[QUOTE="Kevin Rohrer, post: 735647, member: 1260"] There has been lots of discussion on this subject on other boards. As I recall, the rule-of-thumb is that if the runout is <.005, you will not see a difference in those groups as compared to groups with no runout. If you are getting sub-MOA groups at 100-yards, that is pretty good with the type of bullet you are using. And unless I am missing something, your groups will open-up at longer ranges in consistent proportion to the range. If you want to spend money to try and reduce the runout, try getting a seating die that has the bullet sleeve in it. I use Hornady New Dimension dies and like them. Other companies also sell sleeved seating dies, and Vickerman sells one in which YOU manually start the bullet. You can also get the Hornady comparator that in addition to measuring the runout, also has the option to correct it. I have one and it works as advertised, but see paragraph-1 on whether the end result is worth the expense and effort. [/QUOTE]
