Remember I use a chrony, fewer shots doesn't give a good average for velocity. My RA shows about 75fps to 100fps more velocity, averaged, at the starting loads than given in my Speer and Lyman manuals. Not sure why since it's a 22" barrel which is close to the 22" Remington 700 the manuals used to test and publish their data.

Develop your own system to get where you need to be....everyone has a little bit different system.
For example...when I test loadings I usually load 15 of each loading then test. After I get a powder charge locked down I may switch to just messing with seating depth, etc... Trial and error and many range and bench hours...fun. enjoy it.
