[QUOTE="biednick, post: 2781554, member: 123604"] 3 round groups are wholely inadequate for testing either precision or velocity spread. They're useful for discarding loads that are unacceptable, not determining how precise a load is. 10 rounds will give you a pretty good idea of the true performance of a load. It's entirely possible what you saw was just a fluke, and repeating the test with meaningful groups would yield different results. This is also true if you decide to try a tuner. I have found they look good with small groups, but once I shoot a meaningful sample size the difference is insignificant. If you're getting unacceptable precision and don't want to change your powder charge adjusting the seating depth may help. [/QUOTE]
